摘要
东西向构造带是北京地区一条主要的金矿化带。通过分析金矿的赋存规律、成因及其与构造活动的关系,深入探讨了东西向构造带对金矿化形成的有利条件,阐述了该区的找矿前景和方向。认为由深大断裂及大型剥离断层组成的东西向构造带内岩浆活动强烈,裂隙构造发育,为成矿元素的迁移、富集和淀积提供了有利的条件和环境;断裂上盘底部较破碎或裂隙较发育的岩层及下盘顶部的变质杂岩是主要的赋矿部位,是今后该区找矿工作的重点靶区。
The east-west tectonic belt in the area of Beijing is a main gold mineralized belt.By analyzing the distribution law,genesis and relationship with the tectonic activity of gold Minerals,this paper discussed the favorable conditions for gold mineralization which provided by the east-west tectonic belt.It also expounded the direction and prospects of prospecting.The author considered that there is strong magmatic activity and more structural cracks in the east-west tectonic belt which composed of the deep fault and the denudational fault.It provided the favorable conditions and environment for the migration,enrichment and deposition of the ore-forming elements.The bottom of broken rock above the fault plane and the top of metamorphic complexes under the fault plane are the main parts of the ore and the important target of prospecting.
