摘要
砂岩型铀矿成矿铀源的来源是多种多样的,可以是来自盆地周边的蚀源区岩石,也可以是盆地容矿层本身铀的预富集,还可以是来自盆地深部的铀源(包括油田水的铀、构造热液带出的铀等)。重点对影响砂岩型铀矿成矿的蚀源区铀源、容矿层地层铀源及深部油田水铀源的评价方法进行了探讨。
There are various kinds of uranium source leading to the ore-formation of sandstone-type uranium deposits, it may come from rocks in the provenance areas, from uranium pre-enriched ore- hosting horizon themselves of the basin and from the uranium source underneath the basin （including uranium contained in the oilfield water and uranium introduced by tectonic hydrothermal fluids, etc.）. The paper focuses the discussion on the evaluation methods of the uranium source from provenance areas and ore-hosting horizon, and oilfield water from the depth, which effect the ore-formation of sandstone-type uranium deposits.
