What rocks are chemical or potentially chemical sedimentary rocks?

Answer 1

Chemical or potentially chemical sedimentary rocks form through the precipitation of minerals from solution, often in bodies of water. Common examples include limestone, which can form from calcium carbonate precipitating out of seawater, and evaporites like rock salt and gypsum, which result from the evaporation of water in arid environments. Other examples include dolostone, which can form through the alteration of limestone. These rocks often indicate past environmental conditions such as evaporation rates and water chemistry.
