| 摘 要： | 南秧田白钨矿床是中国滇东南地区一个罕见的似层状白钨矿床,矿体赋存在元古界南秧田岩组层状似矽卡岩中。最新的勘查资料表明,该矿床已达超大型矿床规模。笔者通过详细的矿区实地考察,结合室内岩、矿石地球化学分析及国内外典型矿床对比研究,对该矿床似矽卡岩的原岩进行了恢复,得出南秧田白钨矿床似矽卡岩的原岩为海底火山喷发沉积(或热水沉积岩)夹杂部分的陆源碎屑沉积岩,对南秧田层控白钨矿床似矽卡岩进行了成因探讨,认为南秧田白钨矿床似矽卡岩为沉积变质成因矽卡岩,属类矽卡岩系列。

| Abstract: | The Nanyangtian scheelite ore deposit is a rarely-seen layered scheelite deposit in southeastern Yunnan,whose ore body is hosted in the layered skarnoid of Proterozoic Nanyangtian Rock Group.Based on detailed field work in combination with indoor rock geochemical analysis as well as a comparison with typical ore deposits both in China and abroad,the authors carried out restoration of original rock of skarn,found that the original rock of the skarn seems to be submarine volcanic eruption(or hot water) sedime... |
