在对攀西裂谷西部边界的调查过程中,我们在木里地区发现了宽数十公里的混杂堆积带。这条混杂堆积带位于扬子古台块之西,向西与理塘晚古生代火山弧的弧前消减杂岩相接,位于一个大地构造上十分重要的部位。本文将对主要的观察事实做一报道,并对其地质意义作初步的讨论。
During the investigation of the western boundary of the Panxi Rift, we found a few tens of kilometers of mixed accumulation zone in Muli area. This mixed accumulation belt is located in the west of the Yangtze Paleogene and connects westward with the pre-arcuate subduction complex of the Late Paleozoic volcanic arc in Litang and is located in a very important part of the earth’s tectonics. This article will make a report on the main observation facts and give a preliminary discussion of its geological significance.
