陕西铅硐山-东塘子铅锌矿地质特征及找矿方向

铅硐山由于山上有古人采矿留下许多老硐而得名。1985年西北有色地质勘查局七一七总队提交了地质勘探报告,获铅锌金属量112.13万t。2001年在铅硐山西延(东塘子)提交地质详查报告,获铅锌金属量7.32万t,2002年成立了东塘子铅锌矿。铅硐山-东塘子铅锌矿产在古道岭组灰岩与星红铺组千枚岩界面,地层控矿明显,矿体形态产状受铅硐山-东塘子背斜控制突出,具有典型的背斜控矿特征。东塘子铅锌矿是深部找矿成功的典型范例。从地表矿体露头开始→由表到里→由浅到深→顺藤摸瓜寻找隐伏背斜(矿体)的方法是深部找矿行之有效的方法,值得广泛推广。

Geological Characteristics and Prospecting Direction of Lead-Zinc Mine in Shaanxi Qiandongshan-Dongtangzi

Qiandongshan because of its mountains are the ancients left many old underground mining.In 1985 the Northwest Nonferrous Geological Exploration Bureau of geological exploration report submitted to the seven one seven corps, a volume of 1121300 tons of zinc metal.2001 lead cave in Shanxi Yan, Dong Tang Zi) submitted to the geological survey report, won the lead and zinc metal was 7.32 million tons, in 2002 established Dong Tangzi lead-zinc mine.Qiandongshan-Tang Dong sub lead zinc mineral in gudaoling group limestone and Red Star shop phyllite interface, strata bound mineral apparent, orebody shape by emphasizing the control of lead Tong mountain Tong East sub anticline, with a typical anticline ore con-trolling characteristics.The lead and zinc deposit in the East is a typical example of the deep prospecting success..From the beginning of the surface outcrop ore body, from the surface to the inside, from shallow to deep, Shuntengmogua find buried anticline ( orebody) method is deep prospecting effective method, worthy of extensive expansion.
