Basic properties of dolomite
Detrital dolomite: according to its detritusSize can be divided into gravel, sand, dust, dolomite. They are often found in the general dolomite layer in the form of interlayers. Formed in shallow water above or above the intertidal zone, whose debris is formed by waves or currents.
Biogenic dolomite and detrital dolomite: it can be seen that the fossil remains are mostly formed by the replacement of detrital limestone by dolomitization.
Algal dolostone: similar to algal limestone, that is, dolomite composed of algae fossils. Most of dolomite in Proterozoic and Sinian strata belong to this type in China. It may be of primary dolomite type.
Micro - fine dolomite crystal size, crystal shape is quite good, looks rather like sugar, the field available saccharoidal dolostone known, often by other types of dolomite recrystallization and.
Argillaceous dolomite: consisting of less than 0.005 millimeters of argillaceous dolomite, the structure is uniform, with microscopic bedding, few biological residues, sometimes visible in the form of fossils, mostly primary dolomite.
