Law of superposition

The law of superposition is a principle that forms one of the bases of the sciences of geology, paleontology, and other fields pertaining to geological stratigraphy. In its plainest form, it states th
Layer upon layer of rocks on north shore of Isfjord (Svalbard), Norway. Since there is no overturning,[citation needed] the rock at the bottom is older than the rock on the top by the law of superposition.

Relative dating

Relative dating is the science of determining the relative order of past events, without necessarily determining their absolute age. In geology, rock or superficial deposits, fossils and lithologies c

The Permian through Jurassic stratigraphy of the Colorado Plateau area of southeastern Utah is a great example of Original Horizontality and the Law of Superposition, two important ideas used in relative dating. These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park. From top to bottom: Rounded tan domes of the Navajo Sandstone, layered red

Multiple melt inclusions in an olivine crystal. Individual inclusions are oval or round in shape and consist of clear glass, together with a small round vapor bubble and in some cases a small square spinel crystal. The black arrow points to one good example, but there are several others. The occurrence of multiple inclusions within a single crystal is relatively common
