There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers.Detrital sedimentary rocks are mainly classified by the size of their grain. The largest grain is a boulder, followed by a cobble, a pebble, sand, silt and finally the finest grain, which is clay. These grains of sediments are what get cemented together to form sedimentary rocks.Sedimentary rocks form whenever these sediments are deposited and lithified and can be classified based on the size of their grains. Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone.Clastic Sedimentary Rocks . The most common set of sedimentary rocks consists of the granular materials that occur in sediment.

Slate looks very similar to shale, but it is harder and more platy. The rock on the right is gneiss. The light and dark minerals have separated into bands. Gneiss is produced by higher temperature metamorphism. The original rock was different in both cases.Major types of clastic sedimentary rocks are (from fine to coarse constituent clasts): mudstone: clay ("blocky") and shale (splits easily) siltstone sandstone sedimentary conglomerate or breccia. Clastic sedimentary rocks are classified mainly on the basis of texture, with sensible names that refer to the size of material they contain. Classification of Common Rocks: Igneous, Sedimentary, and Metamorphic. A rock is a naturally occurring aggregate of minerals, and certain non-mineral materials such as fossils and glass.

Clastic sedimentary rocks are formed by compaction and cementation of clasts composed of individual mineral grains or pieces of rock. Because their mineralogy varies so much, we generally classify clastic rocks based on grain size rather than composition.CLASTIC. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported by erosion to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.Clastic sedimentary rocks are classified based on the dominant particle size. The Udden-Wentworth grain size scale is commonly used by geologists to classify unconsolidated sediment into three fractions: gravel (>2 mm diameter), sand (1/16 to 2 mm diameter), and mud (1/16 mm diameter).Oct 19, 2023 · Vocabulary Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Conglomerate. Conglomerate is a sedimentary rock formed by the lithification of rounded or sub-rounded gravel (grains larger than 2 mm in diameter). Conglomerate is strongly related to sandstone.
