云南文山官房钨矿区隐伏花岗岩形态预测及找矿

Concealed Granite Form Forecast and Prospecting for Wenshan Guanfang Tungsten Area of Yunnan

通过总结文山官房矿区(团山、半坡及官房矿段)花岗岩形态的特征,运用mapgis及surfer软件推测下伏花岗岩体的产出形态,综合分析矿区地形地貌和钻孔揭露信息得出构造影响隐伏花岗岩的形态、白钨矿多产出于隐伏花岗岩凹陷带及凸起部位且矿体的走向受隐伏岩体的走向影响较大的结论。

By summarizing the characteristic of Wenshan Guanfang mine （Tuanshan, Banpo and Guanfang ore block） granites and using mapgis and suffer software to simulate the outputs form of the underlying granite, we analyzed the topography of the mining area and compared the drilling information with the mimic diagram reference of concealed rock： the results show that structure affected the morphology of hidden granite; Scheelite generally comes from the protruding parts and the recess of the granite, and concealed rock strike has a important impact on the ore body strike.
