内蒙古油房—金厂沟梁一带金多金属矿床构造控制作用及找矿方向探讨

内蒙古油房—金厂沟梁一带金多金属矿床处于华北地块北缘东段古亚洲构造域与滨太平洋构造域不同构造体制的交汇部位。区内东西向构造和北北东—北东向构造是区内主体构造,两者的复合构成了该区的基本构造格局。矿床空间分布规律明显受构造控制,呈现出东西向成带、北东—北北东向成行、分段集中的特征,与区内东西向构造和北东—北北东向构造的成生、发展、演化及其复合控岩控矿作用密切相关。文章从成矿带地质背景、构造控制作用,控矿因素等方面进行分析研究,总结找矿模型,以期对该地区进一步的找矿和研究工作有所指导。

Discussion on structural control and prospecting direction of gold polymetallic deposits in You Fang-Jinchanggouliang area, Inner Mongolia

The gold polymetallic deposits in You Fang-Jinchanggouliang area of Inner Mongolia are located in the eastern section of northern margin of the North China block, where belongs to the intersection of different tectonic mechanisms between the paleo Asian tectonic domain and the Pacific Rim tectonic domain. The E-W and NNE - NE trending structure is the main structure in the area, and the combination of the two constitutes the basic structural framework of the area. The spatial distribution of ore deposits is obviously controlled by structure, and showing the characteristics of distributing along zones in E-W direction, developing in rows in NNE-SSW direction, and concentrating on segments, the distribution is closely related with the formation, development, evolution and the composite rock-control and ore-control function of the E-W and NE-NNE trending structure. Based on the analysis of the geological background, structural control and ore-controlling factors of the metallogenic belt, this paper summarizes the ore prospecting model to provide a guide for further exploration and research in this area.
