| Abstract: | Three angular unconformities found in the field work in the previous Baishan Formation of the Carboniferous in Poziquan area help to subdivide Baishan Formation into four formations. Based on the fossil and isotopic data,L angquan Formation and Poziquan Formation are classified into L ower Carboniferous, while Heishishan Formation and Mazhuangshan Formation into Upper Carboniferous. The sedimentary envi- ronment of the four formations,and crustal evolution and stratigraphic association of the Carboniferous in the Poziquan area are studied,supplying a basis for the stratigraphic subdivision and correlation,and crustal evo- lution and geotectonic study as well as prospecting of the associated minerals. |
