Gypsum: Satin spar, a fibrous variety of gypsum from Derbyshire, England Specimen is approximately 4 inches 10 centimeters across What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite

Other minerals present in shale are quartz, mica, pyrite, and organic matter Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor Geologists estimate that shale represents almost ¾ of the sedimentary rock on the Earths crust
