| 摘 要： | 南盘江—右江盆地具独特的盆地构造演化历史和背景,是西南低温成矿域的重要组成部分,广泛发育有Au-As-Sb-Hg-Tl等低温热液矿床,金锑成矿作用与盆地构造演化密切相关。本文系统总结南盘江—右江盆地构造演化过程和历史,分析盆地演化对沉积地层、沉积相带分布、古地理变迁等的控制作用。盆地内金锑矿床受构造和有利岩性组合控矿明显,结合南盘江—右江盆地内Cu-W-Sn-Pb-Zn-Au-Sb-Hg等矿床空间分布特征及规律,探讨盆地构造演化与金锑成矿作用和成矿效应的关系。类比斑岩-矽卡岩-浅成低温热液型多金属矿床最新研究成果,建立南盘江—右江盆地以陆内斑岩型铜矿床为中心,上部或边部矽卡岩型铜矿床、脉状钨-锡-银-铅-锌矿床和远端低温热液金-银-锑-汞矿床的找矿预测模型,模型对南盘江—右江成矿区深部斑岩型矿床或与斑岩体有关的矽卡岩型矿床的找矿勘查具有重要意义。

| Abstract: | The Nanpanjiang–Youjiang basin,which has a unique history and background of the basin tectonic evolution,is endowed with a diversity of mineral resources in Southwest China.Low-temperature hydrothermal deposits such as Au-As-Sb-Hg-Tl deposits are widely distributed,which are closely related to the long and complex tectonic evolution history of the basin.The gold and antimony deposits in the Nanpanjiang–Youjian basin are obviously controlled by structures and favorable lithology.Complex and multiple tectonic-magmatichydrothermal interactions in the basin were fertile grounds for a wide variety of mineral resources.Major types of deposits in the region include sediment-hosted Au-Sb-Hg deposits,porphyry-related Cu-W-Sn-Pb-Zn skarn deposits,and carbonate-replacement Pb-Zn-Ag-Au deposits.The formation of these deposits was associated with a long and complex tectonic history and development of the basin.In this paper,the authors present a new metallogenic model for the Nanpanjiang–Youjiang basin.Based on this model,the authors hold that the porphyry Cu-Au-Mo deposit is located centrally in a multiphase porphyry stock,grades outward through peripheral proximal Cu-Au-W-Mo skarns to distal Au-and Ag-bearing Zn-Pb carbonate replacements and,at the shallower level of ore districts,to sediments-hosted Au deposits deficient in base metals but carrying abundant As,Sb,Hg and Tl.It is expected that the present emphasis on exploring for shallower level sediments-hosted Au-Sb deposits will increasingly lead to exploration for deeper level porphyry Cu-Au-Mo deposits and porphyry-related skarn systems. |
