扬子地台西缘江浪变质核杂岩体的基本结构,划分为堆垛层、褶叠层及板岩带等三个构造地层系统,其间为构造滑脱面所分割,在该类变质核杂岩体中发育有一个中间流变层。本文建立了堆垛层的新概念,认为它是造山带中深部地壳常见的基本构造型式。同时,阐述了该变质核杂岩体中铜矿的构造空间配置及构造过程对成矿作用的控制,建立了该杂岩体内铜矿的成穹-成矿模式,认为川西雅碧江流域地区有较好的找矿远景。
The basic structure of the Jianglang metamorphic core complex in the western margin of the Yangtze platform is divided into three structural stratigraphic systems, ie, stacking layers, pleat strata and slate strata. During the structural stratigraphic detachment, There is an intermediate rheological layer developed in the rock mass. In this paper, a new concept of stacking layer is established, which is regarded as a common basic structure in deep crust in orogenic belt. At the same time, the tectonic space configuration and the tectonic process of the copper deposits in the metamorphic core complex are described to control the mineralization, and the vault-metallogenic model of the copper deposits in the complex is established. It is considered that the Yabi River Basin The region has a better prospecting prospect.
