江夏花山地区矿山地层研究

Study on mine strata in Huashan Area of Jiangxia

矿山地层研究是找矿工作中的关键一步。花山地区隶属扬子地台成矿区的长江中下游成矿带。由于花山地区第四系覆盖严重,所以多数地层罕有露头,仅有志留纪地层、泥盆纪地层和二叠纪地层的露头广泛出露。区内主要出露地层有志留系坟头组(S_(2)f),泥盆系云台观组(D_(3)y),泥盆系黄家磴组(D_(3)h),石炭系黄龙组(C_(2)h),二叠系孤峰组(P_(2)g),第四系早中更新世的王家店组(Qp_(2)w)和晚更新世的青山组(Qp_(3)q)还有全新世的走马岭组(Qhz)。

The study of mine strata is a key step in the prospecting work.Huashan area belongs to the middle and lower reaches of Yangtze River metallogenic belt of Yangtze Platform metallogenic belt..Due to the serious quaternary overburden in Huashan area,outcrops are rare in most strata,and only the Silurian,Devonian and Permian strata are widely outcrops.The main exposed strata in the area are the Silurian Gravehead Group(S_(2)f),the Devonian Yuntaiguan Formation(D_(3)y),the Huang rung group(D_(3)h),the Carboniferous Huanglong Formation(C_(2)h),and the Permian Gufeng Formation(P_(2)g).The Q4(Qp_(2)w)of the Early-middle Pleistocene Quaternary Period and the Qingshan Formation(Qp3q)of the Late Pleistocene,as well as the Holocene Qala(Qhz).
