相山含铀火山岩、火山构造特征与成矿关系的探讨
|
摘要
相山火山岩盆地主体盖层由早白垩世的流纹英安岩和碎斑熔岩组成,这两套火山岩是主要的含矿岩类,并且与铀多金属矿化有关的垂向蚀变深度达千米。该盆地研究历经60余年,取得一系列丰硕成果,但是对含铀火山岩、火山构造与铀成矿关系的认识仍不透彻。在总结前人资料的基础上,通过对主要含矿火山岩(流纹英安岩和碎斑熔岩)的特征进行分析,对火山盆地构造特征做出总结,讨论了火山岩、火山构造与铀成矿的关系。认为相山含铀火山岩可能经历了多期次的成矿作用,盆地内断裂裂隙以及构造转折处为有利成矿部位,相山火山盆地存在多个火山口,岩浆房、火山通道等火山岩浆停留过的部位可能成矿。
The dominate cover of Xianshan volcanic basin is composed of early Cretaceous rhyodacite and porphyroclastic lava. The rhyodacite and porphyroclastic lava are the main uranium hosted rocks,in which alteration related to uranium mineralization is near one kilometer. Although a series of fruitful results have been achieved after more than 60 years research, the understanding of uraniumbearing volcanic rocks and the relationship between volcanic structure and uranium mineralization is still not thorough. On the basis of summarizing the information of the predecessors, through analysis of characteristic of main ore-bearing volcanic rocks(rhyodacite and porphyroclastic lava), this paper summarized the structure characteristics of volcanic basin and discussed the characteristics of uranium volcanic rocks, and the relationship between volcanic structure and uranium mineralization, It was believed that Xiangshan uranium-bearing may have experienced multistages of mineralization, fault-fissure, and structure turning point in basin. There are many craters in the volcanic basin. There are maybe orebodies in the place where the vocanic magma resided in the magma chamber and the volcanic channel.
