selenite is sedimentary. But selenite is really a mineral not a rock. It can be found in any rock type
Selenite Gypsum is used along with alabaster to prepare dental stones.
Selenite is a form of gypsum, a dense mineral that does not float in water. It is heavier than water, so it will sink rather than float.
The translucent form of gypsum is called selenite. Selenite is a type of gypsum that is clear or white and often found in crystal form. It is prized for its smooth, shiny appearance and light-transmitting properties.
Selenite gypsum
Gypsum and selenite are chemically similar as they both are forms of calcium sulfate with the same chemical formula (CaSO4·2H2O). They have the same crystal structure but differ in their crystal habits - gypsum typically forms as massive white rocks, whereas selenite forms clear and prismatic crystals.
They felt fine until the Selenite Police drove them away from their encampment.
Clear. Sometimes white.
Gypsum is actually a major rock forming mineral. Rock gypsum is a chemical sedimentary rock.
The Density (In My Testings) of Selenite is 1.8666666 repeating
No it is not a salt. Gypsum is a mineral that occurs in nature as flattened and often twinned crystals and transparent cleavable masses called selenite.
Gypsum dihydrate is a mineral form of calcium sulfate with two water molecules attached. It is commonly found in nature as a white, chalky mineral and is often used in construction and as a soil conditioner. When heated, gypsum dihydrate loses its water molecules and forms the mineral anhydrite.
