Keys to the Identification of Sedimentary Rocks

 · Carbonates come in such variety and diversity that only the main types are listed here. Mixed types are forced into one category or another. Also, some rock types are much more common than others and thus some rocks listed below are not represented. We have also mixed rock names from different keys although they may refer to the same thing.

Sinkholes

 · In these areas the formation of underground cavities can form, and catastrophic sinkholes can happen. These rock types are evaporites (salt, gypsum, and anhydrite) and carbonates (limestone and dolomite). Evaporite rocks underlie about 35 to 40 percent of the United States, though in many areas they are buried at great depths.
