摘　　要："南盘江-右江"成矿区地处我国西南,是我国重要的金属矿产资源的富集区。在新的研究成果和找矿突破基础上,结合新的理论发展,本文新设定并命名了"南盘江-右江Sn-Sb-Mn-Zn-Al-Au多金属成矿区",即重新划(修)定的25片重点成矿区(带)之一。通过区域成矿地质背景研究,成矿区内划分了6个III级成矿带,初步建立了南盘江-右江Sn-Sb-Mn-Zn-Al-Au多金属成矿区成矿谱系。综合研究认为,区内矿产以锡、锰、锌、铝土矿、金、钨矿等为主,资源潜力巨大。主攻矿床类型为卡林型金矿、沉积型和堆积型铝土矿、沉积型锰矿、深水沉积-改造型铅锌矿、岩浆热液型钨锡矿,并总结了重要矿床类型的成矿模式。成矿区内圈定了14个远景区,其中10个为重点远景区,4个为远景调查区,远景区的划分指明了下一步的找矿方向和工作部署重点,为国家部署公益性地质调查评价工作提供依据和建议。The Nanpaniang-Youjiang metallogenic belt located in southwestern China is an important metal mineral resources concentration area.Based on the previous study and our prospecting results,this study defined a new metallogenic belt and named it the Nanpaniang-Youjiang Sn-Sb-Mn-Zn-Al-Au metallogenic belt.Six sub-level metallogenic zones were re-classified and a metallogenic lineage was established for the Nanpaniang-Youjiang Sn-Sb-Mn-Zn-Al-Au metallogenic belt.Comprehensive study suggests that this belt rich in Sn,Mn,Zn,Al,Au and Ag is of big resources potential.The main deposit types are carlin-type gold deposits,sedimentary-accumulation type bauxite deposits,sedimentary type manganese deposits,SEDEX type lead-zinc deposits,magmatic hydrothermal type wolfram and tin deposits.The authors also summarized the ore-forming model of main deposits types.The 14 target prospecting areas including 10 key prospective areas and four average areas were defined in the belt.The determination of the ten prospective areas will give direction for the next investigation and work points,providing basis and suggestion for national geological survey and assessment for public service.
