渣滓溪锑钨矿区赋矿地层均为五强溪上段,矿体主要赋存于F3的上盘,有编号的辉锑矿脉共计有77条,工业矿体47条;按与F3距离分为Ⅰ、Ⅱ、Ⅲ脉组,以Ⅰ脉组含矿最佳,Ⅱ脉组次之,Ⅲ脉组含矿性较差。系统总结了渣滓溪锑钨矿区矿化富集规律,结果表明,矿脉成组成带分布,整体呈南东侧伏规律;矿脉明显交汇富集,在倾向上倾角变缓及构造膨胀部位富集,主脉富集程度与F3密切相关;赋矿岩系具有锑钨组合特征,锑钨成生关系反映在各自的矿体赋存于不同序次的断裂中;锑矿脉走向与钨矿层走向近于直交,为锑钨叠加成矿的异体共生矿床。渣滓溪锑钨矿区上部锑钨资源共生,资源的开发潜力巨大。
渣滓溪銻鎢礦區賦礦地層均為五彊溪上段,礦體主要賦存于F3的上盤,有編號的輝銻礦脈共計有77條,工業礦體47條;按與F3距離分為Ⅰ、Ⅱ、Ⅲ脈組,以Ⅰ脈組含礦最佳,Ⅱ脈組次之,Ⅲ脈組含礦性較差。繫統總結瞭渣滓溪銻鎢礦區礦化富集規律,結果錶明,礦脈成組成帶分佈,整體呈南東側伏規律;礦脈明顯交彙富集,在傾嚮上傾角變緩及構造膨脹部位富集,主脈富集程度與F3密切相關;賦礦巖繫具有銻鎢組閤特徵,銻鎢成生關繫反映在各自的礦體賦存于不同序次的斷裂中;銻礦脈走嚮與鎢礦層走嚮近于直交,為銻鎢疊加成礦的異體共生礦床。渣滓溪銻鎢礦區上部銻鎢資源共生,資源的開髮潛力巨大。

Ore-bearing strata in Zhazixi antimony tungsten mining area are all in upper Wuqiangxi ,the ore body mainly occurs in the hanging wall of the F 3 ,stibnite veins number a total of 77 ,and the common industrial ore bodies are 47;according to the distance away from F 3 ,Ⅰ,Ⅱ,Ⅲvein groups are classified .GroupⅠis the best in ore-bearing potentials,II vein group poorer and group Ⅲore veins poorest.The regularity of mineralization Zhazixi antimony tung-sten mining area is systematically summarized .The results show thatveins distribute in groups and belts ,laterally tren-ding SE on the whole;veins enrich in the intersection ,where inclination angle slows ,and in the tectonic expansions;the enrichment degree of main veins is closely related with F 3;the ore-bearing rock systemtakes on combined features of antimony and tungsten ,and the mineralization relation between antimony and tungsten are reflected by the fact that their respective orebodies occur in fractures of different sequence; the trending of antimony veins and tungsten strata cross each other nearly orthogonally ,indicating a symbiosis deposit of combined antimony and tungsten mineralization . There is symbiosis of antimony and tungsten in upper Zhazixi mining , suggesting great resource development poten-tials.
