Gypsum is an extrusive sedimentary rock formed from the evaporation of seawater.
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.
Physical precipitation of gypsum due to the evaporation of seawater produces sedimentary rock called gypsum rock or rock gypsum.
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.

precipitation from seawater
Gypsum is an extrusive sedimentary rock formed from the evaporation of seawater.
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. Also consider Halite.

Dolostone is formed through the replacement of calcium ions in limestone with magnesium ions, a process known as dolomitization. Rock gypsum is formed through the precipitation of minerals from evaporating water, leaving behind gypsum deposits.
You might expect a deposit of rock salt or rock gypsum to have formed in a shallow, evaporating basin such as a salt flat or a desert play. These minerals are often deposited when water evaporates, leaving behind the salt or gypsum crystals.
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.
Evaporites are rock units that are most likely formed from chemical precipitates. These rocks are formed when minerals precipitate out of solution as water evaporates, leaving behind minerals like halite or gypsum.
