相山铀矿田研究新进展

New Research Progress in Xiangshan Uranium Orefield

相山铀矿田位于钦—杭成矿带的北东段的位置,也位于之前一直所称的赣—杭成矿带的中部。它是我国目前已发现的最大火山岩型铀矿田。在这近50年中,对矿田的研究程度较高。相山地区的控矿特征研究并不是新鲜的话题,有关界面控矿的理论,这2年得到了进一步充实。矿田的北部已发现的矿床中,逆冲推覆构造占有较大的比例,与之相关的控矿作用,却涉及的资料较少。在相山铀矿田,基性岩的关注度并不高,笔者将就基性岩的特征进行简要介绍。一直以来,邹—石断裂被认为是控矿主断裂,但最近有新的发现,对之前的结论提出了质疑。

Xiangshan uranium orefield is located in the North East of Qin-Hang metallogenic belt and the middle of Gan-Hang metallogenic belt. And,it is the largest volcanic-type uranium orefield we have found in our country.In the nearly 50 years, the research degree of orefield is so high.The ore-controlling characteristics research of Xiangshan uranium orefield is not a fresh topic. The theory of interface controlling uranium deposits has been further enriched these two years. The most of ore deposits which had been found in northern of orefield were possessed by thrust nappe. But less information were involved in the related ore-controlling roles.In this area, the basite hasn＇t attracted much attention.The characteristics of the basite will be briefly introduced by the author. For a long time, Zou-Shi fracture was considered to be the main fracture controlling ore body. But recently, there has been a new discovery,which has raised questions about the previous conclusions.
