In geology and petrology, a prism is a long, narrow, wedge-shaped sedimentary body with a width to thickness ratio greater than 5 to 1 but less than 50 to 1, and a length 1. Geology (from Greek γη gê, "earth" and λόγος Logos, "speech" lit In Geology, petrology (from Greek πέτρα petra, rock and λόγος logos, knowledge is the study of rocks and the conditions on which Sedimentary rock is one of the three main rock types (the others being igneous and Metamorphic rock) 5 to 3 times its width.
These types of sediments are typically formed during orogenic deformation. Orogeny (Greek for "mountain generating" is the process of natural Mountain building and may be studied as a tectonic structural event as a geographical event and For example, the arkoses found in fault troughs. Arkose (ˈɑrkoʊz is a Detrital Sedimentary rock, specifically a type of Sandstone containing at least 25% Feldspar.
"Prismatic" is also type of mineral habit (appearance of a crystal). Prismatic minerals have crystals that show a uniform cross-section. In Geometry, a cross section is the intersection of a body in 2-dimensional space with a line or of a body in 3-dimensional space with a plane etc
