| 摘 要： | 成矿单元是成矿意义上的地质单元。笔者在继承全国矿产资源潜力评价项目确定的中国成矿单元I级(成矿域)、Ⅱ级(成矿省)和Ⅲ级(成矿区带)最新划分方案的基础上,对东天山—北山地区6个Ⅲ级成矿单元(成矿区带)界线进行修正,并以明显的地层、构造和岩浆带及相关的成矿作用为标志,划分11个IV级成矿单元(成矿亚区带),概述各IV级成矿单元(成矿亚带)地质矿产特征。

| Abstract: | Metallogenic unit is a geological unit on the metallogenic significance. The latest classification scheme about Chinese metallogenic units released by the national mineral resource potential assessment project include level I (metallogenic domain), level II (metallogenic provinces) and level III (metallogenic belts). This article revises the boundaries of the six level III metallogenic units (metallogenic belts) in the East Tianshan-Beishan area on the basis of the inheritance of this classification scheme. Then the six level III metallogenic units are divided into 11 class IV metallogenic units (metallogenic sub-zone)as a symbol of sgnificant stratigraphic, tectonic and magmatic belt and associated mineralization. Furthermore, there is a summary about geology and mineral characteristics of every class IV metallogenic unit (metallogenic subzones). |
