怒江、澜沧江、金沙江地区属青藏高原的东缘。著名的横断山脉及三江峡谷构成了这里独特的岭谷相间的地形。陡峻的岭脊多出露变质岩、混合岩及中酸性侵入岩类;深切的谷地多发育中、基性及中、酸性火山岩、沉积岩,并有基性、超基性岩体的分布。由于其大地构造位置正处在特提斯一喜马拉雅构造域由东西向至南北向转折的部位,又受欧亚古陆与冈瓦纳古陆所夹持,是强烈的活动地带,所以地质构造十分复杂。
The Nujiang, Lancang and Jinshajiang areas belong to the eastern edge of the Qinghai-Tibet Plateau. The famous Hengduan Mountains and Sanjiang Gorge constitute the unique terrain here. The steep Ridge more exposed metamorphic rocks, mixed rocks and acidic intrusive rocks; deep valley in the development of more, the basic and medium, acidic volcanic rocks, sedimentary rocks, and basic, ultrabasic rock mass distribution. Because of its tectonic location is located in the Tethys Himalayan tectonic transition from east to north to north part of the site, but also by the Eurasian and Gondwanaland, Gangener locked in a strong activity zone, so the geological structure Very complicated.
