摘要
Dolomites distribute widely in the lower part of the Late Carboniferous Huanglong Formation in the Anhui segment of the Lower Yangtze.Dolomites include three rock types, mostly rystalline dolomites, secondly breccia dolomites and remnant grain dolomites. Evaporative rocks and sedimentary structures could be found in dolomites in Anhui segment of the Lower Yangtze, so the authors think that dolomites of Huanglong Formation are mainly penecontemporaneous and some are formed by burial dolomitization, breccia dolomites are penecontemporaneous.
