随着普查勘探和科研工作的不断深入,我国花岗岩中各种类型铀矿床不断地被发现,有关矿床成因假说也越来越多。就本区花岗岩中铀矿床而论,成因假说也很不一致,如淋积下降成矿说,古地下热水成矿说,热液(多种成因)深部浸出成矿说以及与岩浆演化分异作用有关的期后热液成矿说等。笔者根据本区及兄弟单位的一些资料,也对区内矿床成因问题进行一些讨论。由于本人
With the deepening of census exploration and scientific research, various types of uranium deposits in granite in China are continuously discovered, and more and more hypotheses about the genesis of the deposits are found. In terms of the uranium deposits in granites in this area, the genesis hypothesis is also very different. For example, as the depositional mineralization is reduced, the mineralization of paleo-underground hot water is said that the deep leaching and mineralization of hydrothermal fluids (or multiple genesis) and their differentiation from the magmatic evolution After the period of hydrothermal mineralization and so on. Based on some information from this district and fraternal units, the author also made some discussions on the causes of deposits in the area. Because of myself
