Quizplus · Accepted Answer

Limestone is the most abundant chemical sedimentary rock, comprising about 10% of all sedimentary rock. It is primarily composed of calcium carbonate, which can be deposited through chemical precipitation or biologically through the accumulation of shells and skeletal fragments of marine organisms. Dolomite is a similar rock that is composed of calcium magnesium carbonate, but it is less abundant than limestone. Chert is a type of sedimentary rock that is primarily composed of silica, and while it is common in certain rock formations, it is not as abundant as limestone. Rock salt, or halite, is a chemical sedimentary rock that forms from the precipitation of salt minerals, but it is not as abundant as limestone.
