相山铀矿田矿床勘查模式探讨

相山铀矿田最后一期大规模火山熔岩喷发结束后,开始了大规模的铀成矿流体活动,在有利的构造部位形成热液活动中心.铀成矿流体在运移过程中,遇到圈闭构造发生矿质沉淀,形成铀矿石.因此,在相山铀矿田可以通过采用“热液活动中心十圈闭构造十多种物探方法”的铀矿床勘查模式,实现找矿新的突破.

Discussion of Uranium Exploration Mode in Xiangshan Uranium Orefield

After the final phase of large-scale lava eruption, large scale ore forming fluid activity was started in xiangshan orefield, and some hydrothermal activity center was formed in the beneficial structural parts; when the ore forming fluid met trap structure in the migration process, the fluid precipitate and form orebody. Therefore we can use the mode as ＂center of hydrothermal activity ＋ trap closed structure ＋many kinds of geophysical technique＂ to explore uranium deposit in Xiangshan orefield so as to get breakthrough in the prospecting.
