柞水—山阳多金属矿集区成矿条件及找矿潜力分析

柞水－山阳盆地发育热水沉积岩和复理石建造，断裂构造和岩浆活动强烈，成矿条件优越，是重要的多金属矿集区．目前，在泥盆系碳酸盐岩建造内发现了Ag—Pb－Cu—Zn矿床，但众多化探异常尚未评价，故找矿潜力较大。笔者认为．在银洞子－桐木沟菱铁银铅锌铜金成矿带、东川－小川铅锌铜金成矿带以及沿山阳－凤镇断裂发育的铜金镍钼（钴）成矿带内，具有寻找热水沉积（改造）型多金属矿、钠长角砾岩型金矿、沉积变质型磁铁矿床及斑岩一矽卡岩型铜（钼）矿床的前景。其中．凤镇断裂北侧干沟－万丈沟－双元沟－土地沟一带、南侧李家砭－冷水沟－张氏沟口一带和穆家庄－肖台地段应是找铜的首选靶区：穆家庄铜矿和银洞子银铅多金属矿等矿床的外围和深部也具有寻找新矿床或矿体的潜力。

Metallogenic conditions and prospecting potential of the Zhashui-Shanyang poly-metal ore cluster

The Zhashui-Shanyang basin is developed with hydrothermal sedimentary rocks and flysch formation,which were reworked by strong magmatism and faulting.The basin has good ore-forming conditions and is now an important ore -cluster area.To date,remarkable Ag -Pb -Cu -Zn deposits have been found in Devonian carbonate strata,with numerous no-evaluated geochemical anomalies,indicating that the basin is potential for ore exploration.In this paper it is suggested that the reworked hydrothermal sedimentary type poly...
