What is another word for nonclastic rock?
Pronunciation: [nˌɒnklˈastɪk ɹˈɒk] (IPA) 
Nonclastic rock refers to sedimentary rock that is formed through chemical processes without any contribution from mechanical agents such as erosion, transportation, and deposition. It is distinguished by its chemical composition, texture, and structure. There are several synonyms for nonclastic rock, including chemical sedimentary rock, evaporitic rock, biogenic rock, and organic sedimentary rock. Chemical sedimentary rocks are formed from the precipitation of minerals from a solution, such as limestone and dolostone. Evaporitic rocks are the result of the drying up of a saltwater basin, such as rock salt and gypsum. Biogenic rocks are formed from the accumulation of organic materials such as coal and coral reefs. Organic sedimentary rocks result from the compaction and consolidation of organic materials such as oil shale and sedimentary phosphates.
