Sandstone is a clastic sedimentary rock composed of sand-sized mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar because they are the most resistant minerals to weathering processes at the Earth's surface, as seen in the Goldich dissolution series. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, yellow, grey, pink and black. Since sandstone beds form visible cliffs and other topographic features, certain colors of sandstone have been identified with certain regions. Rock formations that are composed of sandstone allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Fine-grained aquifers, such as sandstones, are better able to filter out pollutants from the surface than are rocks with cracks and crevices, such as limestone or other rocks fractured by seismic activity. Quartz-bearing sandstone can be changed into quartzite through metamorphism related to tectonic compression within orogenic belts.
Sandstones are clastic in origin. They are formed from cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals; the cements binding these grains together are calcite and silica. Grain sizes in sands are defined within the range of 0.0625 mm to 2 mm. Clays and sediments with smaller grain sizes not visible with the naked eye, including siltstones and shales, are called argillaceous sediments; the formation of sandstone involves two principal stages. First, a layer or layers of sand accumulates as the result of sedimentation, either from water or from air. Sedimentation occurs by the sand settling out from suspension. Once it has accumulated, the sand becomes sandstone when it is compacted by the pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains; the most common cementing materials are silica and calcium carbonate, which are derived either from dissolution or from alteration of the sand after it was buried.
Colors will be tan or yellow. A predominant additional colourant in the southwestern United States is iron oxide, which imparts reddish tints ranging from pink to dark red, with additional manganese imparting a purplish hue. Red sandstones, both Old Red Sandstone and New Red Sandstone, are seen in the Southwest and West of Britain, as well as central Europe and Mongolia; the regularity of the latter favours use as a source for masonry, either as a primary building material or as a facing stone, over other forms of construction. Framework grains are sand-sized detrital fragments; these grains can be classified into several different categories based on their mineral composition: Quartz framework grains are the dominant minerals in most clastic sedimentary rocks. These physical properties allow the quartz grains to survive multiple recycling events, while allowing the grains to display some degree of rounding. Quartz grains evolve from plutonic rock, which are felsic in origin and from older sandstones that have been recycled.
Feldspathic framework grains are the second most abundant mineral in sandstones. Feldspar can be divided into two smaller subdivisions: plagioclase feldspars; the different types of feldspar can be distinguished under a petrographic microscope. Below is a description of the different types of feldspar. Alkali feldspar is a group of minerals in which the chemical composition of the mineral can range from KAlSi3O8 to NaAlSi3O8, this represents a complete solid solution. Plagioclase feldspar is a complex group of solid solution minerals that range in composition from NaAlSi3O8 to CaAl2Si2O8. Lithic framework grains are pieces of ancient source rock that have yet to weather away to individual mineral grains, called lithic fragments or clasts. Lithic fragments can be any fine-grained or coarse-grained igneous, metamorphic, or sedimentary rock, although the most common lithic fragments found in sedimentary rocks are clasts of volcanic rocks. Accessory minerals are all other mineral grains in a sandstone.
Common accessory minerals include micas, olivine and corundum. Many of these accessory grains are more dense than the silicates; these heavy minerals are resistant to weathering and can be used as an indicator of sandstone maturity through the ZTR index. Common heavy minerals include zircon, rutile, magnetite, or other dense, resistant minerals derived from the source rock. Matrix is fine material, present within interstitial pore space between the framework grains; the nature of the matrix within the interstitial pore space results in a twofold classification: Arenites are texturally clean sandstones that are free of or have little matrix. Wackes are texturally dirty sa
Enid Bakewell, played for the English women's cricket team in 12 Tests between 1968 and 1979, in 23 one-day international matches. A right-handed bat and slow left-arm bowler, on her figures she has a strong claim to be regarded as the best all-rounder that the English women's game has produced. In Tests she scored 1,078 runs at an average of 59.88, with 4 centuries, as well as taking 50 wickets at an average of 16.62. In what proved to be her final Test, she scored 68 and 112 not out and took 10 for 75 against West Indies at Edgbaston in 1979, she along with Lynne Thomas set the record for the highest opening run partnership in the history of Women's Cricket World CupIn 2014 Wisden Cricketers' Almanack selected her as one of the five greatest female players of all time. Bakewell was born in Nottinghamshire, she was encouraged to play cricket from an early age. She was educated at the primary school in Newstead and at Brincliffe County Grammar School, Nottingham. After playing for a local club, Notts Casuals WCC, she started to play for the Nottinghamshire county women's team aged 14.
She concentrated on her batting but was encouraged to develop her slow left-arm bowling, which she modelled on Tony Lock. She studied at Dartford College of Physical Education, graduating in 1959, she married an electrical engineer with Rolls Royce. Their daughter was born in 1966. Bakewell was considered for selection for the Test tour to Australia in 1963, she was pregnant and so missed the home Tests against New Zealand in England in 1966. She joined the 1968-69 tour, playing in all three Tests against Australia and all three Tests against New Zealand, she opened the batting in her first Test, against Australia in 1968, made a century on debut, scored centuries opening the batting in the first and second Tests against New Zealand in 1969. Small but quick and athletic, with good footwork, on the tour she achieved a batting average of 39.6 in 29 innings, took 118 wickets at a bowling average of 9.7. In the first Women's World Cup competition in 1973, which England won, she scored 118 in the final match against Australia and took 2/28 in 12 overs.
She played, at age 41, in the 1982 Women's Cricket World Cup, taking 3 for 13 against India at Wanganui and three for 29 against the International XI at Wellington. She played in the three Tests at home against Australia in 1973, the three home Tests against the West Indies in 1979. At Edgbaston in 1979 she scored 68 in the first innings, carried her bat to score 112 not out in the second innings, took 10 for 75 in the match, she continued to play for East Midlands into her 50s. She is an ECB-qualified coach. Bakewell was inducted into the ICC Cricket Hall of Fame in 2012, becoming the third woman cricketer to be thus recognized, she was awarded the MBE in the 2019 New Year Honours.
