方城县二郎庙乡Mo、W多金属异常综合评价及找矿预测

二郎庙钼多金属异常区位于华北陆块南缘的陡垛庄—李仙桥花岗岩带上,为栾川成矿带的东延部分,异常区元素规模大、含量高,异常套合性较好,强度高,对该异常重点开展1:1万地质简测和探槽工程揭露等,在异常区内新发现了7条钼矿化体(带),证明了该异常良好的找矿远景. 从异常区区域成矿构造背景、李仙桥花岗岩体、物化探等方面探讨了二郎庙异常区的成矿条件,认为该异常区成矿地质条件十分优越,找矿前景巨大,建议在已取得的地质成果基础上,进一步对二郎庙钼、钨多金属异常区进行全面深入的研究,加大对异常区外围及深部的找矿投入,有望找出品位较高、规模较大、具有较大经济价值的钼矿床.

Comprehensive Evaluation and Prospecting Forecast for Abnormal Mo,W of Erlangmiao Village

The discovery of Erlangmiao molybdenum mineralization objects is based on the geo -chemical prospecting anomaly .Erlangmiao molybdenum , tungsten polymetallic anomaly area lies on the Douduozhuang -Lixianqiao granite belt of the southern margin of North China block , which be-longs to the extension of the east Luanchuan fault zone .1:50 000 gauge of waterways sediment suggests that the element is much bigger and higher in the anomaly area .The measured soil profile shows that there is a good and immensely strong matching in the anomaly .1:10 000 simplified ge-ological mapping , mine survey and trench project in the anomaly have found seven new molybde-num mineralization objects ,which means a good prospecting potential .From metallogenic tectonic background in this anomaly area , Lixianqiao granite tectonic , as well as geophysical and geochemi-cal exploration, these conditions of Erlangmiao anomaly area are discussed in the paper .The re-sults indicate that the ore-forming geological conditions of the abnormal area are very superior , e-normous prospecting potential .Based on the obtained geological achievements , we suggest that fur-ther comprehensive studies for Erlangmiao molybdenum , tungsten polymetallic anomaly area should be conducted , and increase prospecting investment in the depth and peripheral abnormal area , to find out the molybdenum and tungsten deposit with higher grade , bigger mineralization object , and greater economic value .
