List of rock types Wikipedia

The following is a list of rock types recognized by geologists. There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type. Additionally, different classification systems exist for each major type of rock.

The rock is of Ordovician age. Turbidity sequence is typically composed of many alternating layers of siltstone (very fine sandstone) and mud. Silt settles faster than clay minerals do and therefore every current is composed of two distinct layers (there may be even more).

Sedimentary rocks include conglomerate, sandstone, siltstone, shale, argillite, limestone, and dolomite. Metamorphic rocks include gneiss, schist, phyllite, slate, marble, hornfels, and skarn and various other types of metaigneous and metasedimentary rocks. Many types of minerals, both common and obscure, are also present.

Types of Rocks Igneous Sedimentary Rocks Metamorphic

Sedimentary Rock. The sedimentary rocks are formed by the deposition and subsequent cementation of that material within bodies of water and at the surface of the earth. The process that causes various organic materials and minerals to settle in a place is termed as sedimentation. The particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, the

Description of Minerals and Rocks ISGS

If the magma cools slowly, some individual mineral grains have the opportunity to grow larger than others. If the magma cools quickly, as lava or basalt does, the separate mineral grains are small. Igneous rocks are classified on the basis of the size and arrangement of the individual crystals and the kinds of minerals present (table 2).

Three Types of Rock: Igneous, Sedimentary & Metamorphic AMNH

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. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon
