摘要
圈定隐伏花岗岩体，是广西寻找隐伏金属矿床的关键。笔者根据近年的科研成果，以航磁为主，在广西系统地圈定隐伏花岗岩体九十余处，总结了它们的预测标志和圈定边界、估算埋深的方法，特别是圈定弱一无磁性岩体的方法，讨论了它们的分布规律，探讨了具不同磁场类型的岩体的成矿专属性及深部找矿的前景。
The delineation of comealed granite bodies seems to be the key to the prospecting for concealed metallic deposits. Based on the research achievements gained in recent years, the author, using mainly aeromagnetic survey, has delineated more than 90 concealed granite bodices,summed up their prognostic indicators and the methods for outlining these bodies and estimating their buried depths, es[ecially the method for delineating weakly magnetic-nonmagnetic rock bodies,and dealt with their distribution regularity. In addition, a tentative discussion is given on metallogenic specializations of granite bodies with different types of magnetic fields as well as prospects of ore prospecting at depth.
