摘要
本文利用重磁场资料对我国南方一些花岗岩体的侵位状态和岩浆动力场进行了分析 ,并按动力场的强弱对岩体进行了分类。根据重力资料对苗儿山 越城岭、诸广山和贵东花岗岩体的反演计算 ,讨论了这些岩体的深部分布形态 ,提出了岩浆流动的 3种方式 ,指出了富大铀矿床。
The emplacement status and dynamic field of magma of some granitic massifs in the south of China are analyzed by using gravimetric and aeromagnetic data in this paper,and granitic massifs are classified according to their intensity of dynamic field Based on the inverse calculation of gravimetric data of Miaoershan?Yuechengling,Zhuguangshan and Guidong granitic massifs,the deep distribution form of these massifs is discussed,then three movement ways of magma flow are proposed,and finally,the emplacement sites of rich?large uranium deposits and area of uranium ore concentration,are pointed out,and the close relation between aeromagnetic anomalies and rich?large uranium deposits are pointed out as well
