Noncarbonate chemical sedimentary rocks in large part exhibit crystalline texture, with individual mineral grains forming an interlocking arrangement. Depositional setting is an insignificant factor …Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals. Chemical rocks are classified mainly by the composition of minerals in the rock. ... Non-clastic textures are found chiefly in rocks that have precipitated chemically from water (chemical sedimentary rocks), such as limestone, dolomite and chert. …Dolostones commonly produces a conchoidal fracture when hammered or on fresh, broken surfaces, similar to that of other fine-grained crystalline sedimentary rocks like limestone and chert. Moreover, like all carbonate rocks , dolostones are subject to slow dissolution in water at ambient conditions, which produces karstic features on outcrops ...
