渣滓溪锑钨矿床位于雪峰弧形成矿构造带中段，主要赋存于板溪群五强溪组上段的一套火山－碎屑岩沉积浅变质岩系中。其锑矿床产于北西向控矿构造中，矿脉成组分布，具有相似的等距和方向性；钨矿床产于五强溪组上段第三层石英砂岩、凝灰质砂岩中，矿体受岩性及层间节理裂隙控制，构成“层控型”钨矿层。锑矿脉走向与钨矿层走向近于直交，形成异体共生矿床。通过对该矿床成矿条件及其成矿机理分析，为矿区深边部及近外围的找矿勘查提供可靠的地质依据。

Zhazixi Antimony -Tungsten Deposit is located in the middle of Xuefeng arc tectonic mineralization belt.The ores are mainly deposited in a volcano -clastic sedimentary epimetamorphic rock system in upper Wuqiangxi Formation of Banxi Group.The antimony deposit occurs in the NW-trending ore-controlling structure with ore veins distributed in groups that are with equidistant and directional similarities;the tungsten deposit occurs in the third layer of quartz sandstone and tuffaceous sandstone of upper Wuqiangxi Formation,and the orebody is controlled by lithology and interlayer joints forming a"strata-bound"tungsten layer.The antimony lode crossesthe tungsten layer nearly or-thogonally,forming a parabiosis deposit.The analysis of the metallogenic conditions and mechanism of this depositpro-vides a reliable geological basis for the deep and near peripheral prospecting .
