陕西穆家庄铜矿床地质地球化学特征及找矿标志

Geological-Geochemical Characteristics and Prospecting Indication of the Mujiazhuang Copper Deposit, Shaanxi Province

穆家庄铜矿床形成于柞水．山阳泥盆纪热水沉积盆地中受同生断裂控制的次级深水盆地中，矿体呈透镜状、似层状沿北西西向构造破碎带产出，是秦岭泥盆系中热水沉积一构造改造型的典型矿床之一。在总结矿区地质特征、地球化学特征的基础上，建立了综合找矿标志，为区内找矿提供了新的勘查思路。

The Mujiazhuang Cu deposit is located in the secondary hydrothermal deposit basin controlled by the contemporaneous faults in the Devonian Zhashui-Shanyang hydrothermal basin. Orebodies occurring in forms of lens and stratabound-like along the NWW-trending structural zone represent the typical deposit of hydrothermal deposit-tectonic alteration in the Devonian strata of the Qinling Mountains. Based on geology and geochemistry, combined prospecting indications for copper deposit in this region are discussed.
