我国西南部怒江、澜沧江、金沙江流域,地区辽阔,地跨滇西川西藏东青海南部广大地区,矿产资源丰富。三江成矿带不仅是我国著名的有色、贵金属成矿带,而且是我国在今后一段时期内实施“跨世纪勘查工程”最有远景的地区。本文总结了三江地区金属矿床的分布特征,并从大地构造岩浆地层的角度阐明其地质背景。
In the southwest of China, the Nujiang, Lancang and Jinsha River basins are vast in area and span vast areas of the southern part of eastern Qinghai in Tibet in western Yunnan and have rich mineral resources. Sanjiang metallogenic belt is not only China’s famous non-ferrous and precious metal metallogenic belt, but also the most prospective area for our country to implement “Trans-century exploration project” in the coming period. This paper summarizes the distribution characteristics of the metal deposits in Sanjiang area and clarifies its geological background from the perspective of tectonic magmatic strata.
