| 摘 要： | 大通河盆地为一上古生代—中新生代断陷盆地,沉积持续时间长,后期构造作用强烈。通过对盆地内二叠系沉积相及铜矿化特征分析,认为铜矿化物质来源于北祁连古陆核,经剥蚀—沉积形成了含铜二叠系陆相杂色砂岩,后期断裂构造及热液活动更加强化了铜矿化的作用。

| Abstract: | Datonghe basin is a upper Paleozoic-middle Cenozoic depression basin with durable sedimentation and late strong tectonic process.Based on the analysis on Permian sediment phases and characteristics of copper mineralization,it is concluded that the matter for copper mineralization originated in paleocontinent nucleus and copper containing Permian continent mottle sandstone were formed by erosion and deposition and late structure,and hydrthermal activities further strengthened copper mineralization. |
