摘要
新山矿区为一铁、铜、铅锌多金属矿,矿体呈似层状、透镜状赋存于上三叠统桃子树组（T3tz）中,矿体产状与围岩层产状一致.其中铁铜矿主要产于桃子树组下段之顶部,铅锌矿主要产于桃子树组下段之下部.矿床成因属于火山喷发沉积～改造（层控碳酸盐）型矿床.
It is a Fe, Cu, Pb -Zn multimetallic deposit. The ore body is stratoid, lenticular, in Upper Triassic Taozishu Formation （ T3 tz）. The occurrence of ore body is consistent with that of the wall rock. The Fe - Cu deposit of it is mainly in the top of Taozishu Formation Lower Member, whereas the Pb -Zn deposit is mainly in the lower part of Taozishu Formation Lower Member. It belongs to the volcanic eruption sedimentation -reformation （stratabound carbonate） type deposit.
