Marble is a metamorphic rock composed of recrystallized carbonate minerals, most calcite or dolomite. Marble is not foliated, although there are exceptions. In geology, the term "marble" refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is used for sculpture and as a building material; the word "marble" derives from the Ancient Greek μάρμαρον, from μάρμαρος, "crystalline rock, shining stone" from the verb μαρμαίρω, "to flash, gleam". This stem is the ancestor of the English word "marmoreal", meaning "marble-like." While the English term "marble" resembles the French marbre, most other European languages, more resemble the original Ancient Greek. Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most limestone or dolomite rock. Metamorphism causes variable recrystallization of the original carbonate mineral grains; the resulting marble rock is composed of an interlocking mosaic of carbonate crystals.
Primary sedimentary textures and structures of the original carbonate rock have been modified or destroyed. Pure white marble is the result of metamorphism of a pure limestone or dolomite protolith; the characteristic swirls and veins of many colored marble varieties are due to various mineral impurities such as clay, sand, iron oxides, or chert which were present as grains or layers in the limestone. Green coloration is due to serpentine resulting from magnesium-rich limestone or dolostone with silica impurities; these various impurities have been mobilized and recrystallized by the intense pressure and heat of the metamorphism. Examples of notable marble varieties and locations: White marble has been prized for its use in sculptures since classical times; this preference has to do with its softness, which made it easier to carve, relative isotropy and homogeneity, a relative resistance to shattering. The low index of refraction of calcite allows light to penetrate several millimeters into the stone before being scattered out, resulting in the characteristic waxy look which gives "life" to marble sculptures of any kind, why many sculptors preferred and still prefer marble for sculpting.
Construction marble is a stone, composed of calcite, dolomite or serpentine, capable of taking a polish. More in construction the dimension stone trade, the term "marble" is used for any crystalline calcitic rock useful as building stone. For example, Tennessee marble is a dense granular fossiliferous gray to pink to maroon Ordovician limestone, that geologists call the Holston Formation. Ashgabat, the capital city of Turkmenistan, was recorded in the 2013 Guinness Book of Records as having the world's highest concentration of white marble buildings. According to the United States Geological Survey, U. S. domestic marble production in 2006 was 46,400 tons valued at about $18.1 million, compared to 72,300 tons valued at $18.9 million in 2005. Crushed marble production in 2006 was 11.8 million tons valued at $116 million, of which 6.5 million tons was finely ground calcium carbonate and the rest was construction aggregate. For comparison, 2005 crushed marble production was 7.76 million tons valued at $58.7 million, of which 4.8 million tons was finely ground calcium carbonate and the rest was construction aggregate.
U. S. dimension marble demand is about 1.3 million tons. The DSAN World Demand for Marble Index has shown a growth of 12% annually for the 2000–2006 period, compared to 10.5% annually for the 2000–2005 period. The largest dimension marble application is tile. In 1998, marble production was dominated by 4 countries that accounted for half of world production of marble and decorative stone. Italy and China were the world leaders, each representing 16% of world production, while Spain and India produced 9% and 8%, respectively. Italy is the world leader in marble export, with 20% share in global marble production, followed by China with 16%, India with 10%, Spain with 6%, Portugal with 5%. Dust produced by cutting marble could cause lung disease but more research needs to be carried out on whether dust filters and other safety products reduce this risk; the Occupational Safety and Health Administration has set the legal limit for marble exposure in the workplace as 15 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday.
The National Institute for Occupational Safety and Health has set a recommended exposure limit of 10 mg/m3 total exposure and 5 mg/m3 respiratory exposure over an 8-hour workday. Acids damage marble, because the calcium carbonate in marble reacts with them, releasing carbon dioxide: CaCO3 + 2H+ → Ca2+ + CO2 + H2O Thus, vinegar or other acidic solutions should never be used on marble. Outdoor marble statues, gravestones, or other marble structures are damaged by acid rain; the haloalkaliphilic methylotrophic bacterium Methylophaga murata was isolated from deteriorating marble in the Kremlin. Bacterial and fungal degradation was detected in four samples of marble from Milan cathedral; as the favorite medium for Greek and Roman sculptors and architects, marble has become a cultural symbol of tradition and refined taste. Its varied and colorful patterns make i
Mungia is a town and municipality located in the province of Biscay, in the Basque Country of northern Spain. The town has 17,000 inhabitants. Mungia lies 20 metres above sea level in an area full of open spaces, with a landscape of rolling hills; the more important mountains nearby are Jata. There are many small streams and underground springs, such as the Atxuri, Lauromendi, Atebarri, or Mantzorriko Erreka, which are all tributaries of the Butroi river and provide water to the numerous fountains built in the town. In the past those waters helped to run more than 20 mills. Although there are still traces which show that the area where Mungia stands today was inhabited in prehistoric times the first documented reference we have dates back to the year 1051, when an abbot from Mungia confirmed a gift from the Lord of Biscay to the Monastery of San Millán de la Cogolla. At the beginning, whose name comes from the Basque Mune - Ganean, was not much more than a tiny village with a dispersed population.
At that time the church was the only focus of the community, but the settlement began to acquire its own significance as a result of the presence of an abbot and of its location in a strategic pass between the interior of the feudal holding and the coast at Bermeo, which had begun to stand out as an export harbour. Under these conditions, important families belonging to the nobility settled in the surrounding areas of the village and built there their tower houses; the economic power of these noblemen was based on landholdings. However, as a consequence of a stockbreeding and agricultural crisis at the end of the 13th century, these families began to suffer. To face this situation they sought hard to improve their income streams, the easiest recourse they could have was to violence. On the pretext of "being more worthy" they fought with each other, their peasants were decimated and deprived of their scarce belongings, or involved in faction fights themselves. In the area of Mungia, we find representatives of two factions: the Billela family, part of the Ganboar faction. and the Butroi family which led the faction of Oinaz.
As the tower houses of both families were next to each other their fights were a common event. The borough of Mungia came to be as a consequence of this situation; some of the inhabitants in the area, witnessing the outrages of the nobility, requested the Lord of Biscay, the Infante Juan, to grant the title of borough to their town, in order to enable the fortification of the town and thus effective defence against attacks. By this means on 1 August 1376, under the Fueros of Logroño, the borough of Mungia was created in the centre of an anteiglesia similar in extent to the Parish) of the same name. Both belonged to the merindad of Uribe, each had an autonomous municipality. In the same way, they each had their own representation in the Juntas of Gernika, numbering 69 for the anteiglesia and 15 for the borough, but the fact of designating a borough did not avoid a great number of fights in the area. Thus, there were various episodes of different nature, arising from the wars between the factions.
Just to name a few of the most important of those small skirmishes, we mention the battle of Berteiz or the battle of Mungia, which took place on 27 April 1479 and in which the factions of Oinaz and Ganboa, enemies up to that moment, formed an alliance to fight against the Earl of Haro. Leaving these episodes aside, life in Mungia is thought to have been calm. Economic activity was based on farming, with a few mills located on the banks of the many streams which washed the area, as well as small craft workshops settled down in the borough; the daily round was disturbed. In 1602 there was a fire, a larger fire 1778 on 9 November with fourteen of the main buildings in the village burned down. From this time, to prevent accidents happening, all inflammable products such as straw and coal were stored in a place outside the enceinte; this site was known as Atzekaldeta, a basque name which refers to the location of the place in the rear part of the town. Thus time passed for both the borough of Mungia and the anteiglesia of the same name.
They were independent entities, although they joined together for the sake of some services and improvements. Thus, the school was common to both, when the time arrived to canalise the water from the Gondramendi mountain to the village both shared the expenditure. Little by little, more tasks were performed together and as a result of this co-operation bigger problems arose leading to the idea of joining both bodies and becoming one unique entity; this happened on 6 October 1900. The fountain which today lies in Beko Kale, in front of Arnaga, is the symbol of this unity under the motto "Biak bat eta biena". Up to 1936 life for the inhabitants passed by without major events, based on fundamental rural and agricultural activities, but with an i
Abadiño is a town located in the province of Biscay, in the autonomous community of Basque Country, in the north of Spain, about 35 km from the provincial capital of Bilbao. The area of the municipality is about 36 km2 and according to the 2014 census, the population is 7504; the original name of the town was Abadiano Celayeta. Abadiño is located on the N-636 road a few kilometres to the southeast of Durango in the province of Biscay in northern Spain; the town is in a broad valley formed by the Urkiola Rivers. Livestock farming is practised here on the flat valley floor, to the south the land rises to form the Urkiola mountain range; the lower slopes are clad in natural woodland of oak and pine, the higher parts consist of limestone peaks with gullies and caves and are included in the Urkiola Natural Park. The town of Abadiño has a number of historic buildings; the Muntsaratz Tower is a good example of ninth century Renaissance architecture. The Sanctuary of San Antonio is a church inside the Urkiola Natural Park.
The Astola Manor House was one of the political and administrative centres of the Merindad de Durango region. It was purchased by the Merindad in 1576 and was subsequently used as a courthouse, as the residency of the local lieutenant, as the local gaol and as the district archive; the Gederiaga Complex includes the Chapel of San Salvador. This was an ancient "oath chapel" in which general assemblies of the authorities of Merindad de Durango valley were held. There are mountain bike riding and horse riding facilities near the town. There are the main one being that of the patron saint, Santa Domingo; this takes place on May 12th and the succeeding days and there is much music and dancing in the town. The Festival of San Blas takes place on February 3rd, at this event there is a livestock fair. Another festival, that of San Antonio, is celebrated on June 13th near his sanctuary in Urkiola. Athletic Bilbao players Ustaritz Aldekoaotalora and Ander Iturraspe were born in Abadiño. ABADIÑO in the Bernardo Estornés Lasa - Auñamendi Encyclopedia Abadiño Official Website In Basque and Spanish
Spain the Kingdom of Spain, is a country located in Europe. Its continental European territory is situated on the Iberian Peninsula, its territory includes two archipelagoes: the Canary Islands off the coast of Africa, the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country. Several small islands in the Alboran Sea are part of Spanish territory; the country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar. With an area of 505,990 km2, Spain is the largest country in Southern Europe, the second largest country in Western Europe and the European Union, the fourth largest country in the European continent. By population, Spain is the fifth in the European Union. Spain's capital and largest city is Madrid. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago. Iberian cultures along with ancient Phoenician, Greek and Carthaginian settlements developed on the peninsula until it came under Roman rule around 200 BCE, after which the region was named Hispania, based on the earlier Phoenician name Spn or Spania.
At the end of the Western Roman Empire the Germanic tribal confederations migrated from Central Europe, invaded the Iberian peninsula and established independent realms in its western provinces, including the Suebi and Vandals. The Visigoths would forcibly integrate all remaining independent territories in the peninsula, including Byzantine provinces, into the Kingdom of Toledo, which more or less unified politically and all the former Roman provinces or successor kingdoms of what was documented as Hispania. In the early eighth century the Visigothic Kingdom fell to the Moors of the Umayyad Islamic Caliphate, who arrived to rule most of the peninsula in the year 726, leaving only a handful of small Christian realms in the north and lasting up to seven centuries in the Kingdom of Granada; this led to many wars during a long reconquering period across the Iberian Peninsula, which led to the creation of the Kingdom of Leon, Kingdom of Castile, Kingdom of Aragon and Kingdom of Navarre as the main Christian kingdoms to face the invasion.
Following the Moorish conquest, Europeans began a gradual process of retaking the region known as the Reconquista, which by the late 15th century culminated in the emergence of Spain as a unified country under the Catholic Monarchs. Until Aragon had been an independent kingdom, which had expanded toward the eastern Mediterranean, incorporating Sicily and Naples, had competed with Genoa and Venice. In the early modern period, Spain became the world's first global empire and the most powerful country in the world, leaving a large cultural and linguistic legacy that includes more than 570 million Hispanophones, making Spanish the world's second-most spoken native language, after Mandarin Chinese. During the Golden Age there were many advancements in the arts, with world-famous painters such as Diego Velázquez; the most famous Spanish literary work, Don Quixote, was published during the Golden Age. Spain hosts the world's third-largest number of UNESCO World Heritage Sites. Spain is a secular parliamentary democracy and a parliamentary monarchy, with King Felipe VI as head of state.
It is a major developed country and a high income country, with the world's fourteenth largest economy by nominal GDP and sixteenth largest by purchasing power parity. It is a member of the United Nations, the European Union, the Eurozone, the Council of Europe, the Organization of Ibero-American States, the Union for the Mediterranean, the North Atlantic Treaty Organization, the Organisation for Economic Co-operation and Development, Organization for Security and Co-operation in Europe, the Schengen Area, the World Trade Organization and many other international organisations. While not an official member, Spain has a "Permanent Invitation" to the G20 summits, participating in every summit, which makes Spain a de facto member of the group; the origins of the Roman name Hispania, from which the modern name España was derived, are uncertain due to inadequate evidence, although it is documented that the Phoenicians and Carthaginians referred to the region as Spania, therefore the most accepted etymology is a Semitic-Phoenician one.
Down the centuries there have been a number of accounts and hypotheses: The Renaissance scholar Antonio de Nebrija proposed that the word Hispania evolved from the Iberian word Hispalis, meaning "city of the western world". Jesús Luis Cunchillos argues that the root of the term span is the Phoenician word spy, meaning "to forge metals". Therefore, i-spn-ya would mean "the land where metals are forged", it may be a derivation of the Phoenician I-Shpania, meaning "island of rabbits", "land of rabbits" or "edge", a reference to Spain's location at the end of the Mediterranean. The word in question means "Hyrax" due to Phoenicians confusing the two animals. Hispania may derive from the poetic use of the term Hesperia, reflecting the Greek perception of Italy as a "western land" or "land of the setting sun" (Hesperia

Valle de Trápaga-Trapagaran
Valle de Trápaga-Trapagaran is a town and municipality located in the province of Biscay, in the autonomous community of Basque Country, northern Spain. It is located near Barakaldo and Ortuella. Iron ore has been mined here since Roman times and the two parts of the municipality, which are at different altitudes, are linked by a funicular railway. Valle de Trápaga-Trapagaran is located 12 km from Bilbao in the Triano mountain range in the province of Biscay; the municipality is divided into two zones. Ninety percent of the population live in the lower zone in the neighbourhoods of Durañona, El Juncal, Galindo-Salcedillo, Valle de Trápaga, the administrative centre, Trápaga-Caused and Ugarte; the upper zone is in the mountains of Triano, the neighbourhoods here are La Arboleda, Matamoros-Burzaco, Parcocha-Barrionuevo and La Reineta. The European route E70 running along the north coast of Spain passes the town; the upper zone is connected by a funicular railway. The town of Valle de Trápaga-Trapagaran expanded with the mining activities and most of the buildings date from the late nineteenth and early twentieth centuries.
The church of San José Obrero is built in Romanesque style while the churcht of San Juan Bautista is neoclassical, as is the city hall, built in the first decade of the twentieth century. Iron ore has been mined here since Roman times and there was a great increase in mining activity and residential development in the upper zone after the building of the railway in the late nineteenth century; the iron ore deposits became exhausted in the mid-twentieth century and now the area is residential and recreational, although traces of its industrial past remain. Many of the former mines have been flooded and turned into recreational areas with sports facilities and lakes stocked with fish.

Instituto Nacional de Estadística (Spain)
The National Statistics Institute is the official agency in Spain that collects statistics about demography and Spanish society. It is an autonomous organization in Spain responsible for overall coordination of statistical services of the General State Administration in monitoring and supervision of technical procedures; every 10 years, this organisation conducts a national census. The last census took place in 2011. Through the official website one can follow all the updates of different fields of study; the oldest statistics agency of Spain and the predecessor of the current agency was the General Statistics Commission of the Kingdom, created on November 3, 1856 during the reign of Isabella II. The so-then Prime Minister Narváez approved a decree creating this body and ordering that people with recognized ability in this matter were part of it. On May 1, 1861, the Commission change its name to General Statistics Board and their first work was to do a population census. By a decree of September 12, 1870, Prime Minister Serrano created the Geographic Institute and in 1873 this Institute change its name to Geographic and Statistic Institute assuming the competences of the General Statistics Board.
In 1890, the titularity of the agency was transferred from the Prime Minister's Office to the Ministry of Development. Between 1921 and 1939, change its name many times. In the same way, the agency was transferred from a ministry to another, passing through the Deputy Prime Minister's Office, the Ministry of the Presidency and the Ministry of Labour; the National Statistics Institute was created following the Law of December 31, 1945, published in the BOE of January 3, 1946, with a mission to develop and refine the demographic and social statistics existing, creating new statistics and coordination with the statistical offices of provincial and municipal areas. At the end of 1964 the first computer was installed at the INE, it was a first-generation IBM 1401, for which a team was formed consisting of four statistics faculty and ten technicians. In the four years following it was possible that said. INE Website
