华南花岗质潜火山杂岩与富铀矿的成矿关系及找矿前景

Formation and Uranium Explorating Prospecting of Subvolcanic Granitic Complex and Rich Uranium Ore Deposit in South China

本文探讨了华南地区火山岩型或花岗岩型富铀矿，与岩浆旋回晚期的构造－岩浆活动的关系。火山岩型富铀矿离不开大规模火山活动的晚期次火山活动；而花岗岩型富铀矿，则与主侵入晚期的中细粒、不等粒小岩体密切相关。经过长期研究，根据岩浆作用性质，将这套独具特色并与富铀矿的形成息息相关的岩石。

The rich uranium ore deposits are all closely related to tectono magmatism of late magmatic cycle whether volcanic types or granitic typesin south China.Volcanic type rich uranium deposit has closely relationship with sub volcanic activity,and granitic type rich uranium deposit is also closely related to mid fine,unegual particle small massif in late main vasion stage.Based on characteristics of magmatism, We name the rock sub volcanic granite complex, which is a unique style and closely related to the formation of rich uranium ore deposit
