摘　　要：甘肃省宕昌县瓦石沟辉锑矿是近年来在西秦岭地区新发现的具有一定开发价值的辉锑矿床,是通过持续的化探异常查证取得的找矿成果。通过对成矿区域地质背景及地球化学特征分析,结合矿区详细地质资料可知,辉锑矿床主要赋存于石英砂岩和泥质粉砂岩中,矿化程度与硅化及萤石化等围岩蚀变成正相关,初步认定为瓦石沟辉锑矿属于低温热液裂隙充填型脉状矿床。Dangchang County in Gansu Province tile stone-drain Stibnite ore has certain development value stibnite bed in recent years in the western Qinling area of recent discovery.It was the result of the prospecting achievement which continued to search exceptionally verifies obtains.This article we analyzed the geological background and the geochemistry characteristic of minerogenetic region,and with the help of the further unifies the mining area detailed geological data which on-the-spot investigation obtains to be possible to know.The stibnite bed mainly lives in quartz-sandstone and the pelitic siltstone,the mineralization degree and silicification or firefly petrochemical become are being positively related,it recognized initially belongs to the low temperature hydrothermal crevasse backfill vein ore bed for the tile stone-drain stibnite.
