黔东地区下古生界清虚洞组、熬溪组、杨家湾组和红花园组,既是Hg、Sb、Au、Pb、Zn金属矿床的容矿层位,也是中国南方著名的古油藏或残余油气藏的储集层,两者间存在着密切的空间关系和成因联系。金属矿床和古油藏的产状基本一致,均赋存于灰岩和白云岩的缝隙、孔洞和晶间。垂向上,
The Lower Paleozoic Qingxudong Formation, the Aoxi Formation, the Yangjiawan Formation and the Honghuayuan Formation in the eastern part of Guizhou Province are not only the ore-bearing layers of Hg, Sb, Au, Pb and Zn metal deposits, but also the well-known ancient reservoirs in South China Or reservoirs of residual oil and gas reservoirs, there is close spatial relationship and genetic connection between the two. Metal deposits and paleo-reservoirs are basically the same in shape and occur in the gaps, pores and intergranules of limestone and dolomite. Vertical,
