河南栾川罗村钼矿水系沉积物地球化学特征及找矿方向

Stream Sediment Anomalies and Range of Reconnaissance in Luocun Porphyry Mo Deposit,Luanchuan County,Henan Province

栾川县罗村钼矿区位于东秦岭钼矿带栾川矿集区内,地处华北地台南缘。分析矿了区1∶5万水系沉积物地球化学特征,对元素的分布和富集规律进行了总结,圈定了单元素异常和组合异常,并对异常进行了解译,圈定了重点找矿地段,指明了找矿方向。研究结果表明:罗村岩体其外接触带是钼矿化富集的有利部位,矿区东北部和西南部具有良好的寻找铅银锌多金属矿的找矿潜力,中部Au、As、Hg、Cu组合异常较好,应加强异常查证,实现金矿的找矿突破。

Luocun molybdenum mining area in Luanchuan county is located in Luanchuan mineral concentration zone of the East Qinling molybdenum mining belt,on the southern edge of the North China Platform.The paper analyzes the geochemical characteristics of 1∶50000 water system sediments in the mining area,summarizes the distribution and enrichment patterns of elements,delineates single element anomalies and combination anomalies,interprets anomalies,identifies key mineral exploration areas,and points out the direction of mineral exploration.The research results indicate that the outer contact zone of Luocun rock mass is a favorable location for molybdenum mineralization enrichment;the northeast and southwest parts of the mining area have good prospecting potential for lead,silver,and zinc polymetallic deposits;the combination of Au,As,Hg,and Cu anomalies in the central region is relatively good,and anomaly verification should be strengthened to achieve breakthroughs in gold exploration.
