内蒙古锡盟南部与冀西北地区铅锌银金成矿地质条件对比

Comparative Analysis of Pb-Zn-Ag-Au Mineral-formation Condition in the South Xilin Gol League of Inner Mongolia with in the Northwest Hebei

内蒙古锡盟南部与冀西北地区,中生代以前的地质历史发展结果,包括大地构造背景、基本构造格架、构造运动发展过程、古老变质岩系分布、矿化作用等方面有极大的不同。燕山运动使这两个地区有了许多显著的共同点,如构造形迹、构造形式、形成建造、热液活动及成矿时代等方面。本文指出,通过加强构造地质、燕山期岩浆活动、蚀变与矿化等方面的研究,在锡盟南部地区找到与冀西北地区同类型的金及多金属矿床是有希望的。

To compare the South Xilin Gol League, Inner Mongolia with the Northwest Hebei, the result of the pre-mesozoic geological history process is very different from each other, includes the tectonic setting, the basic tectonic framework, the tectonic movement process, the distribution of old metamorphics system, and the mineralization etc.. There are many outstanding common grounds after Yanshan movement both of the two area. These common grounds include the structural feature, the tectonic form, the formation formed during Yanshan movement, the hydrothermal activity, and the mineralization period etc..Author is convinced that it promises to discover the gold-polymetal ore deposit similar to the Northwest Hebei in the South, Xilin Gol League, Inner Mongolia, by way of enhancing study the tectonics, magmatic activity during Yanshan movement, alteration and mineralization etc..
