* Evaporites: These rocks form when water evaporates, leaving behind dissolved minerals. Common evaporites include rock salt (halite), gypsum, and potash.
* Travertine: This rock forms when calcium carbonate precipitates from groundwater, often in areas with hot springs or caves.
* Dolostone: This rock is formed when magnesium replaces some of the calcium in limestone, usually through chemical reactions in groundwater.
* Chert: This rock is composed of silica (SiO2), which can be precipitated from water or from the dissolution of silica-rich organisms like diatoms.
It's important to note that not all chemical sedimentary rocks form directly from dissolved minerals. Some, like chert, can form from the accumulation and lithification of biogenic materials.
