位于川西北的岷江断裂,是一个引入嘱目的构造形迹,它和松潘、漳腊一带的矿产,地震现象至关密切。本文以比较丰富的实际村料描绘了这一构造形迹的特征。岷江断裂沿岷江和涪江上源南北延伸近百公里,具有如下的特征:1.断裂有明显的“分段性”。断裂北段和南段走向近南北,力学性质为压性或压扭性。断裂中段走向北北东,具张(扭)性。断裂的分段表现于地貌上尤为明显。
The Minjiang Fault, located in the northwest of Sichuan Province, is a tectonic trace of the purpose of this project. It is closely related to the mineral and seismic phenomena in Songpan and Zhangla. In this paper, the characteristics of this tectonic trace are depicted with abundant actual village material. The Minjiang fault extends nearly 100 km north and south along the Minjiang River and the upper reaches of the Fujiang River, and has the following characteristics: 1. The fracture has obviously “fragmentation”. The northern and southern sections of the fault are approaching north and south, and their mechanical properties are compressive or compressive. The middle of the fault to the north-east, with Zhang (torsional). Fracture performance is particularly evident in the landform.
