中文摘要：

南温河矿区茅坪矿段白钨矿床位于滇东南老君山多金属成矿区,隶属于滇东南—桂西锡钨多金属成矿带。经野外地质调查研究,在茅坪矿段发现了3个较大规模的矿化蚀变带,显示出该矿段有较强的白钨矿成矿潜力。分析表明：（1）茅坪矿段第Ⅱ层矿连续性较好,有一定的潜在利用价值;（2）茅坪矿段与地层、岩性、变质相系、岩浆热液活动等关系紧密,是成矿的有利部位;（3）该矿段中WO3平均品位为0.38%,预计白钨的资源量为3 845.38 t。矿段达到可开采规模,具有较好的找矿前景。结合区域地质背景、矿床地质特征以及矿体特征,对矿区内控矿因素、矿床成因以及找矿标志进行了探讨,认为该矿段白钨矿为与燕山期花岗岩体有关的岩浆热液交代成因。

英文摘要：

The field geological investigations show that three relatively large-scaled mineralization alteration zones exist in Maoping ore deposit,which indicates that this ore block has a high scheelite metallogenetic potentiality.The second layer of the Maoping ore block is characteristic of good continuity.It has a favorable mineralization position due to its close connection with stratum,lithological characters,metamorphic facies series and magmatic-hydrothermal event.The wolframine reserves is expected up to 3 845.38 tons with the average grade of 0.38 %.This ore of large and medium size has a good prospecting future.Based on the regional geological background,ore deposit geological characteristics and ore body characteristics,we discuss the ore-controlling factors,ore-forming genesis and prospecting indicators.
