吉林大东南岔金铜矿床地质特征及控矿条件分析

Analysis of geological features and ore-controlling conditions of the Dadongnancha gold-copper deposits in Jilin Province

本文简要地介绍了矿区的成矿地质背景及主要矿床的地质特征,重点阐述了控矿因素,分析了区内下古生界五道沟群变质岩系、华力西晚期至燕山期侵入岩以及主要断裂构造与成矿作用的关系。通过对大东南岔金铜矿床控矿条件进行分析、评价,为区内及外围找矿提供依据。

In this paper, metallogenic geological background and main geological features were introduced, focusing on the ore-controlling factors, the relationship was analyzed, that among Lower Paleozoic Wudaogou Group metamorphic rocks system, Late Variscan to Yanshanian intrusive rock, main fracture structure and mineralization. Through analyze and evaluate ore-controlling conditions of Dadongnancha gold-copper deposit, we provide the basis for the district and periphery prospecting.
