甘肃龙首山矿床的成矿动力学机制研究

Study on metallogenic dynamic mechanism of Longshoushan deposit in Gansu Province

在地球亿万年的地质变迁中各地区形成了独一无二的矿山,矿床的形成和矿产资源的赋存离不开岩体内部结构的压力,研究甘肃龙首山矿床的成矿动力学机制。节理产状孕育矿床布局、变质基底制约成矿岩性、脉间距控制脉体生长、局部与区域动力转换影响成矿效果这四个角度分析动力学机制,为不同时期下的矿产资源组成提供研究思路。

In the hundreds of millions of years of geological changes of the earth,unique mines have been formed in various regions.The formation of deposits and the occurrence of mineral resources are inseparable from the pressure of the internal structure of rock mass.The metallogenic dynamic mechanism of Longshoushan deposit in Gansu Province is studied.The dynamic mechanism is analyzed from the four perspectives of joint occurrence breeding deposit layout,metamorphic basement restricting metallogenic lithology,vein spacing controlling vein growth,and local and regional dynamic transformation affecting metallogenic effect,so as to provide research ideas for the composition of mineral resources in different periods.
