Gypsum is which type of rock.
Sedimentary rocks are the most common type of rock on our earth’s surface. In general, they make up roughly 75% of the rocks you see around you. The difference between sandstone and mudrocks are; when there are sand sized fragments, it is considered sandstone. If there is silt and clay sized fragments, then they are mud rocks.
Gypsum is readily identified by its softness (a fingernail scratches it). Gypsum comes as clear crystals that display one perfect cleavage (selenite), as blocks of featureless white rock (alabaster), and as silky fibrous blocks (satin spar). Halite (next page) breaks into cubes (three cleavages at right angles) and tastes like table salt.Apr 21, 2021 · Gypsum is one of the most common minerals in Oklahoma.
