摘　　要：桂西北丹池锡矿带是中国重要的有色金属成矿带之一,主要由芒场、大厂、五圩3个矿田组成,发育多个锡多金属矿床。东南亚是世界著名的锡矿带,被称为东南亚特提斯锡矿带,覆盖中国西南三江、缅甸、泰国、马来西亚、印度尼西亚等多个国家和地区。本文系统对比了两个成矿带成矿地质背景、矿床地质特征,发现桂西北丹池锡矿带与东南亚特提斯锡矿带具有一定的联系性,均与特提斯洋演化存在一定的联系。类比东南亚特提斯锡矿带已发现矿床类型,桂西北丹池锡矿带未来也应关注隐伏岩体顶部的云英岩型及分异程度较高的花岗岩中的伟晶岩型锡矿床。The Danchi tin metallogenic belt in northwestern Guangxi is one of the important non-ferrous metal metallogenic belts in China.It is mainly composed of Mangchang,Dachang,and Wuxu ore fields which include multiple tin polymetallic deposits.The southeastern Asia is a world-famous tin ore belt called the Southeastern Asia Tethys tin metallogenic belt and covers many countries and areas such as the Sanjiang district in southwestern China,Myanmar,Thailand,Malaysia and Indonesia.Based on a systematic comparison on the metallogenic geological background and typical ore deposits of the two metallogenic belts synthesized,the authors proposed that the Danchi tin metallogenic belt in northwestern Guangxi has a certain connection with the Southeastern Asia Tethys tin metallogenic belt,and both of them show affinity with the evolution of the Tethys.Analogous to the ore deposit types in Southeastern Asia Tethys tin metallogenic belt,the Danchi tin metallogenic belt in northwestern Guangxi should be also paid attention to the lomitic type on the top of the concealed intrusive body and the pegmatite type tin deposit in the highly differentiated granite in the future.
