涂光炽先生(1983)强调要重视元古界的找矿工作。以湖南来说,许多重要的金、锑、钨矿床几乎产于元古界,如近年在湘西某地发现的新类型金-锑-砷矿床(化),即其一例。矿床位于新华夏系构造带的北缘,出露地层有第三系、志留系、奥陶系、寒武系、震旦系及元古界板溪群五强溪组,呈北东走向的带状分布。其南约25公里,有加里东期的二长花岗岩、花岗闪长岩出露,面积达1069平方公里,同位素年龄测定(锆石)分别为421、360×10~6年。区域构造以复式背斜为主,轴向北东。区域性的北东向F_1、F_2压性断裂使五强溪组上段
Mr. Tu Guangchi (1983) emphasized that attention should be paid to the prospecting work in the Proterozoic. In Hunan, many important gold, antimony and tungsten deposits are almost produced in the Proterozoic. For example, a new type of gold-antimony-arsenic deposit discovered in a place in western Hunan in recent years is one example. The deposit is located in the northern margin of the structural belt of the Xinhuaxia system. There are Tertiary, Silurian, Ordovician, Cambrian, Sinian and Wuqiangxi formations of Banxi Group in the Proterozoic in the exposed strata, The ribbon distribution. Its southern about 25 km, the Caledonian monzonite granite, granodiorite exposed area of 1069 square kilometers, isotopic dating (zircon) were 421, 360 × 10-6 years. The regional structure is dominated by multiple anticlines and is axially northerly. The regional north-east F_1, F_2 compressive faults make the upper part of Wuqiangxi Formation
