内蒙古赤峰老府金多金属矿区地质、地球化学特征

全面研究和总结内蒙古赤峰老府金多金属矿区地球化学特征、矿体特征,探讨了其成矿机制并分析了矿床的控矿条件及找矿标志,对矿区今后的找矿工作有一定的指导意义。基本过程包括:(1)对区域内土壤地球化学元素进行数理统计分析;(2)探讨矿石的结构特点和矿体的构造特点,从而分析矿床的控矿条件与找矿标志。得出结论如下:(1)区内大面积出露太古界建平群地层为金矿的形成提供了物质来源;(2)燕山期大面积的岩浆活动为金矿的形成提供了热动力条件;(3)北东向断裂构造控制了矿体的产出。

Inner Mongolia Chifeng Laofujin polymetallic mining area geological, geochemical characteristics

On the basis of a comprehensive study and summarize the geochemical characteristics and ore body characteristics of the Laofu gold polymetallic ore deposit in Chifeng city,Inner Mongolia province,the ore-forming mechanism of the ore deposits is discussed.In addition,analysis on the ore-controlling conditions and prospecting marks,the mining area of future prospecting work has some significance.The basic content including:(1)Analysis on the area soil geochemical element by mathematical statistics.(2)Discuss the structure characteristics of the ore and the structure of the ore body characteristics,thereby analysis of the ore-controlling conditions and ore prospecting marks.Conclusions are as follows:(1)In the region,large area of the exposed jianping stratum of Archean group,provide the material sources for the formation of gold ore;(2)Large-scale of the magma activity in theYanshanian movement,Provide thermal dynamic conditions for the formation of gold ore;(3)The northeast direction of fracture structure control the ore body form.
