| 摘 要： | 川西龙门山中段彭州式铜矿形成于岛弧构造环境,其形成经历了晋宁期幔源火山沉积和褶皱变形、印支期-燕山期以来强烈的构造挤压和破坏。根据研究区地层形变的各种构造形迹,将区内构造体系划分为北北西向"多"字型和北东向华夏式两种构造体系。"多"字型构造体系是在晋宁期右行剪切作用下形成北东—北北东向的褶皱带,后经印支期-燕山期以来的左行旋转至北北西而保留至今,表现为黄水河群组成的复式背、向斜褶皱带;华夏式构造体系显示了印支期以来北东—南西方向强大的挤压,表现为前期的叠瓦状断裂和后期的"飞来峰"构造。两种构造体系共同控制着彭州式铜矿床的形成及改造。根据二者的平面展布形态、构造出露特征及其动力学标志,将其划分为包容和交接两种复合关系,即"多"字型构造体系包容于华夏式构造体系中,在研究区南部二者呈反接关系。

| Abstract: | The Pengzhou copper mine area in the middle section of Longmenshan mountains was formed in an island-arc tectonic environment. During its formation,it undergone the mantle-derived volcanic desposition and deformation of folds in the Jinning period,and Indosinian-Yanshannian strong tectonic compression and destruction. According to the different tectonic systems,the studied area can be devided into two kinds of tectonic systems:the NNW-trending multifont style and NE-trending cathaysoid style. The multifont ... |
