中文摘要:
      勐往-曼卖地区位于临沧-勐海锡、稀有稀土多金属成矿亚带南端,主体发育于临沧-勐海岩浆弧带上,花岗岩风化壳发育,成矿母岩、气候、地形地貌特征有利,离子型稀土矿成矿条件优越。本文对该区离子吸附型稀土矿进行了系统的调查和研究,从成矿地质背景、成矿母岩及矿体赋存特征、成矿控制条件等方面较为详细地分析了勐往-曼卖地区离子吸附型稀土矿的成矿地质特征,进而总结该区稀土矿成矿规律,结合1:5万矿调工作成果,对该区稀土矿找矿潜力进行了初步评价。
英文摘要:
      The Mengwang-Manmai area, Yunnan Province is located at the southern end of the Lincang-Menghai tin and rare-earth polymetallic mineralization subzone, where the main ore body developed on the Lincang-Menghai magmatic arc belt. It hosts a lot of granite weathering crusts as well as other favorable features such as metallogenic rocks, climate, topographic and geomorphology, especially ion type rare earth ore. This paper presents a systematic survey and study on these deposits, focusing on ore-forming geological setting, metallogenic mother rocks and orebody characteristics, ore-control conditions. Then we summarizes the metallogenic regularity of rare earth ores in this area. Combining with the 1:50000 mine survey in this area, this paper makes a preliminary evaluation on its prospecting potential of rare earth ores.
