摘要
白马山——龙山东西向构造隆起带控制了区域钨锑金矿床的展布,龙山背斜和李家冲背斜控制了谢家山金锑矿床的就位。谢家山金锑矿床主要的赋矿地层为震旦系下统江口组含砾砂质板岩;主要的含矿断裂有北西西向、北北东向和北东向,以北西西向为主;主要代表为4号脉,其次北东向的1、2、5号脉和北北东向的7号脉均见到较好的工业矿体。多期次多阶段成矿、有利的地层岩性、复杂的构造环境为成矿作用提供热源和物源,形成了中低温热液型金锑矿床。文章明确提出了区内边深部找矿的具体思路。
The regional W-Sb-Au distribution is controlled by the EW-trending Baimashan-Longshan uplift structure, and the Xicjiashan Au-Sb deposit is controlled by Longshan anticline and Lijiachong anticline. The ore-bearing strata are gravel slate of Lower Simian system; The mineralized fracture were NWW-trending, NNE-trending and NE-trending, the NWW strike was the most in which the No. 4 vein represented mainly, then were the No. 1, No.2 and No.5 vein of NE strike and No.7 vein of NNE strike which were all discovered good commercial orebody.Lamprophyre veins were discovered in borehole. Multi-stages mineralization, advantageous for- mation lithology, complicated structural environment and concealed magmatic rocks provided the heat source and provenance of minerali- zation ,which formed the medium and low temperature hydrothermal Au-Sb deposit. The approach of prospecting in deep and outer areas was clearly put forwarded.
