包括龙门山、东昆仑—西秦岭南沿和横断山在内的三角地区,是青藏高原的一部分。由于该区地质构造十分复杂,对于它的大地构造演化过程,各家发表了不少的看法。尤其近数年内,在探讨区内是否存在欧亚大陆和冈瓦那大陆两者的碰撞结合带等地质构造问题上,提出了一些不同的见解。 Including the Longmen Mountain, East Kunlun - the southern edge of the West Qinling Mountains and the Hengduan Mountains, including the Triangle region, is part of the Qinghai-Tibet Plateau. Due to the complex geological structure in this area, many opinions have been published on the evolution of its tectonic tectonics. In particular, in recent years, some different opinions have been put forward on the exploration of geological structures in the area such as the collision zone between the Eurasian continent and the Gondwanaland.
