In which environment might you expect a deposit of rock salt or rock gypsum to have formed?
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.
What rocks contain gypsum?
Gypsum is commonly found in sedimentary rocks such as limestone, shale, and sandstone. It forms from the evaporation of water-soluble minerals in these rocks, leaving behind the mineral gypsum as a product.
Dolostone and rock gypsum are formed by what process?
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.
What is an example of a gypsum?
An example of gypsum is the mineral commonly used in making plaster of Paris for construction and sculpting purposes. It is a soft sulfate mineral composed of calcium sulfate dihydrate.
Rock salt and rock gypsum are common examples of a group of chemical sedimentary rocks called?
Evaporites. These rocks are formed from the evaporation of saline waters and are commonly found in arid environments such as deserts. They typically contain minerals like halite (salt) and gypsum.
