Types of Rocks and Minerals. (Holt Science and Technology Earth Science pg. 95 - 111
Igneous Rock: There is two types of coarse's, there is fine grained and coarse grained. They can form into volcanic necks, batholiths, sills, stocks, and dikes. Extrusive igneous rocks are rocks that form at a result of volcanic activity at or near the Earth's surface.
Sedimentary Rock: Shale is one of the most fine grained sedimentary rocks. Organic sedimentary rocks form from shells and calcium carbonate from the oceans or seas. Most sedimentary rocks have many strata or layers in them.
Metamorphic Rock: Foliated is the texture of metamorphic rock in which the mineral grains are arranged in plains or bands. If the minerals Calcite, Quartz, and Hematite go through intense heat and pressure the metamorphic rock garnet is created. Non foliated is the texture of metamorphic rock in which the mineral grains are not arranged in planes.
