摘要
通过在河南省栾川县葛条坪地区开展1∶50000水系沉积物测量,总结了区域主要成矿元素的分布型式、元素富集与分散规律,发现Mo、W、Au、Ag、Cu、Pb、Zn等成矿元素存在局部富集现象,尤其是Mo的富集系数(K)为全区最高(1.53)。在综合分析区域成矿地质条件的基础上,对优选的AS-33综合异常,有针对性地开展了1∶10000土壤地球化学测量,发现Mo异常重现性好,且伴生有W、Cu等元素组合,呈现水平分带现象,并具有热液型Mo矿异常特点。通过槽探工程揭露,共圈出钼矿(化)体12条,钨矿体1条,钨矿化体4条,取得了较好的找矿效果。结合上述分析,建立了钼矿的综合找矿模型,圈出了5处钨钼铅锌多金属矿找矿靶区,对于栾川地区钼钨矿的找矿工作有一定的参考价值。
Through 1∶50000 stream sediment survey in Getiaoping area in Luanchuan County,Henan Province,the dis-tribution pattern,enrichment and dispersion of main ore-forming elements were summarized.It was found that there were local enrichment phenomena of Mo,W,Au,Ag,Cu,Pb,Zn and other ore-forming elements,especially the enrichment coefficient(K)of Mo element was the highest(1.53)in the whole area.On the basis of comprehensive analysis of regional metallogenic geo-logical conditions,1∶10000 soil geochemical survey was deployed to the optimal AS-33 comprehensive anomaly.The Mo anom-aly has good recurrence,and is associated with W,Cu and other elements combination,showing horizontal zonation phenome-non,and has the characteristics of hydrothermal Mo anomaly.Through trough exploration,12 molybdenum ore bodies,1 tung-sten ore body and 4 tungsten mineralized bodies have been ringed,and good prospecting results have been obtained.Based on the above analysis results,the comprehensive prospecting model of molybdenum ore is established,and five prospecting targets of tungsten,molybdenum,lead and zinc polymetallic ore are delineated.It has certain reference value for the prospecting of mo-lybdenum and tungsten ore in Luanchuan area.
