汝阳王坪西沟大型铅锌银矿床,属构造蚀变岩型热液矿床,主要工业矿体呈似层状或大透镜状赋存于断裂破碎带中。矿床产状与矿带一致,属陡斜倾矿体,在走向或倾向上呈舒缓波状,膨缩特征明显。铅含量大于锌,银以类质同象赋存于方铅矿品格中,铅与银呈正比变化。诚然,在能圈出富矿体的铅锌矿体部位,也是银矿体的分布空间;矿石组构方面,硫化矿石结构主要有半自形-它形粒状结构为主;构造则以细脉浸染状构造和脉状块状构造为主。
汝暘王坪西溝大型鉛鋅銀礦床,屬構造蝕變巖型熱液礦床,主要工業礦體呈似層狀或大透鏡狀賦存于斷裂破碎帶中。礦床產狀與礦帶一緻,屬陡斜傾礦體,在走嚮或傾嚮上呈舒緩波狀,膨縮特徵明顯。鉛含量大于鋅,銀以類質同象賦存于方鉛礦品格中,鉛與銀呈正比變化。誠然,在能圈齣富礦體的鉛鋅礦體部位,也是銀礦體的分佈空間;礦石組構方麵,硫化礦石結構主要有半自形-它形粒狀結構為主;構造則以細脈浸染狀構造和脈狀塊狀構造為主。
