【摘要】 文章系统论述了相山铀矿田的成矿特征,从时空尺度对成矿物质来源进行了探讨,结合成矿的构造-岩浆-地球动力学背景分析,研究了相山火山盆地成矿热液系统的形成和演化,认为相山铀矿田成矿流体系统是受区域构造环境制约、火山岩浆期后热液系统演化的客观产物。火山岩浆期后成矿热液系统在时间上延续了大约50 Ma,但在不同时间域内其活动空间有异,并由此制约着矿田内铀矿化的时空分布。文章还对矿田内深入找矿提出了建议。更多还原

【Abstract】 This paper has systematically described uranium metallogenic characteristics of Xiangshan ore field.Sources of metallogenic materials are discussed in different temporal and spatial scale.Combining with background analysis of metallogenic tectonic-magmatic-geodynamics,formation and evolution of metallogenic hydrothermal solution system in Xiangshan volcanic basin are studied.Metallogenic hydrothermal solution system in Xiangshan ore field is considered as the objective product of systematic evolution of hydrothermal solution in post volcanic magma constrained by regional tectonic environment.In time scale,metallogenic hydrothermal solution system developed for about 50 Ma,but its active spaces varied in different time domains.So temporal and spatial distribution of uranium mineralization is constrained.Further exploration for the ore field is also suggested in this paper.更多还原
