新疆东准噶尔金矿成因类型及地质特征

GENETIC TYPES AND GEOLOGICAL FEATURES OF Au DEPOSITS IN EAST ZHUNGEER REGION

东准噶尔是金、锡等多金属矿产远景区。金矿 (化 )点多达 1 2 0余处 ,具有密集成群、成带分布特点 ,绝大多数分布在卡拉麦里—莫钦乌拉超壳断裂带及其附近。在对东准噶尔成矿地质背景和大量金矿床深入系统地分析研究基础上 ,划分出 4类金矿的主要成因类型。同时 ,着重讨论了各类金矿主要地质特征 ,目的在于正确反映矿床的成矿规律 。

The east Zhungeer region is a prospect for Au, Sn polymetal mineral resources. There are more than 120 Au dposits (camps) occuring in groups and belts. Most of the Au deposits are located along or near kalamaili Moqinwula deep fault which extends to depth bellow crust. Based on the geological background and systematic researches of Au depooits in the region 4 genetic types are divided and their major geological features are discussed aiming at reflecfing the proper ore forming regularity and supplying references for further Au propecting assessment.
