Question

Quizplus · Accepted Answer

Nonclastic textures are textures that are not composed of fragments or grains that have been cemented together, but rather are made up of chemical or organic material that has precipitated or accumulated. Limestones are the most common example of nonclastic sedimentary rocks, as they are formed from the accumulation of calcium carbonate shells and skeletons of marine organisms. Cherty conglomerates (A) and boulder breccias (B) are both clastic rocks, formed from the cementation of rock fragments. Sandstones (C) can be either clastic or nonclastic, depending on their composition and mode of formation.
