prismatic

adj. of a prism, resembling a prism; multi-faceted, varied, diverse

In geology and petrology, prismatic, or sometimes just called "prism", refers to a usually 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 1.5 to 3 times its width. These types of sediments are typically formed during orogenic deformation. For example, the arkoses found in fault troughs. Prismatic is also type of mineral habit ( appearance of a crystal ). Prismatic minerals have crystals that show a uniform cross-section.
