摘要
For many years in the past, the authors have amassed a great deal of materials on measured stratigraphic profiles and tests in the area. On this basis, by reference to rocks and stratigraphy in Anhui Province, this paper made a specific division of rocks and stratigraphic units in the Huaibei stratigraphic sub-zone and pointed out lithological features and typical boundary markers of each formation and each member, including contact relations between each stratigrpahic unit;secondly, by using a large quantity of testing and analytical data, it systematically studied the substance composition of Early Paleozoic rocks and stratigraphy in the Huaibei stratigraphic sub-zone, and concluded the averages of 3 minerals (calcite, dolomite and quartz), 8 chemical components (CaO, MgO, SiO2, Al2O3, K2O, Na2O, TFe, P2O5) and 9 trace elements (Cu, Mo, Co, Ni, Sr, Ba, Ti, Mn, B) in each formation or member, providing abundant basic data for regional quantitative stratigraphy and facilitating the study on the ore host of endogenic metallic deposit.
