天姆尖破火山口地球物理特征

Geophysical characteristics of Tianmujian caldera

本文系统论述了天姆尖地区地层、岩石的重、磁参数特征和该区重磁异常的分布特征 ,并利用这些特征对天姆尖地区地质构造、隐伏 (半隐伏 )岩体、深部构造和火山构造进行了推断和解释 ,得出了该区具有寻找富大火山岩型铀矿远景的结论。

In this paper,the stratigraphy,and gravimetric and magnetic parameters of rocks,as well as the distribution of gravimetric and magnetic anomalies in Tianmujian area are systematically discussed.Then,the geologic structures,concealed (semi concealed) intrusive massifs,deep structures and volcanic structures are inferred and interpreted.Finally,a conclusion is made that the study area is favorable for locating rich large volcanic type uranium deposits.
