大堡区铅锌矿资源勘查中的成矿地质条件及成因分析OA
Geological Conditions and Genesis Analysis of Lead-Zinc Mineral Resources Exploration in Dabao District
针对大堡区铅锌矿地质工作程度较低、系统性的成矿地质条件与成因分析尚不深入的现实问题,本文依托矿区地质勘查资料,从区域地层、构造、岩浆岩及物化探异常等方面入手,系统分析了大堡区铅锌矿的成矿地质条件与矿床成因.结果表明:铅锌矿体赋存于F26 断层灰岩破碎带中,呈似层状、局部透镜状,属中低温热液充填交代型矿床.该研究可为大堡区后续矿产资源的进一步勘查部署与开发决策提供地质依据.
In response to the low level of geological work and the lack of in-depth analysis of the ore-forming geological conditions and genesis of the lead-zinc mine in Dabao District,this article relies on geological exploration data of the mining area and systematically analyzes the ore-forming geological conditions and genesis of the lead-zinc mine in Dabao District from the aspects of regional stratigraphy,structure,magmatic rocks,and physical and chemical exploration anomalies.The results indicate that the lead-zinc ore body occurs in the fractured zone of the F26 fault limestone,presenting a layered and locally lens shaped structure,and belongs to a medium low temperature hydrothermal filling and metasomatism type deposit.This study can provide geological basis for further exploration and development decisions of mineral resources in Dabao District.
