Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
First of all, Gypsum is a mineral, and Rock Gypsum is a rock, don't get them confused. Second of all, no they aren't. Rock Gypsum is a sedimentary rock, and an alternate name for it is Alabaster.
the color for the gypsum rock is lik ewhite
Chemical sedimentary rock is created by precipitation of minerals out of, or evaporation from, saturated solutions that are high in dissolved minerals. Rock gypsum and rock salt are two examples.
This is known as an evaporite, examples include Halite, Gypsum and certain types of Limestone.
precipitation from seawater
Gypsum
Gypsum is formed underwater, usually between layers of shale and limestone. When the water evaporates and the area dries, the gypsum becomes solid "rock" gypsum.

Gypsum is a mineral that was formed by layers of sediment , fine particles, that were deposited over a period of time, and then subjected to geologic forces.
A chemical sedimentary rock, such as rock salt or rock gypsum.
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
Rock gypsum is formed by precipitation from saturated solutions that are composed primarily of dissolved gypsum. In this case, there is no true sediment, only the solution containing the dissolved mineral that was originally present in weathered and eroded rock.
