Initial Analysis on Tectonic and Magmatism of Xinqiao Mining Area in Tongling of Anhui Province

摘要

There are significant hiatus between Devonian Wutong and Carboniferous Huanglong formation in Xinqiao mining area of Tongling. The two formations have very different lithology, Wutong formation is mainly continental clastic sediments, while Huanglong formation is carbonate rocks. The unconformity interface between Devonian Wutong formation and Carboniferous Huanglong formation is structural weak part, favors the aggregation of ore-forming elements. Magmatism mineralization forms significant industrial value layered massive sulfide ore body and structural weak part is as a major seam position.
