Age assignment and correlation of the Dolomite of the Lower Huanglong Limestone in Jiangsu, Zhejiang and Anhui |
| |
| Abstract: | The dolomite of the Lower Huanglong Limestone is widely distributed in Jiangsu, Zhejiang and Anhui, and contains different faunas. Based on fusulinids, corals and conodonts, major paleontologists agree that the dolomite in North Region (Nanjing, Chaoxien and Wuwei) belongs to Late Early Carboniferous, whereas that in South Region (Yixin, Guande, Xuancheng and Guichi) to Early Middle Carboniferous. Because the lithological characters of the dolomite in both South and North Regions are basically alike and overlain by the crystalline limestone of upper Huang-long Limestone, a few people thought them to be the same layer or to have obviously diachro-nous character. |
