摘要
湘南有色金属矿床的形成和分布主要受构造的控制。多数与花岗岩活动有关,并赋存一定的地层层位。断裂和岩体都有明显的重磁场标志。本文总结了两类不同成因系列花岗岩类的重磁场特征,阐明了区内航磁区域异常主要与骑田岭—千里山等4大岩基有关,并推断了局部异常与浅部岩体或岩带有关。最后提出了11个找矿远景区。
The mineralization and distribution of poiymetallic deposits in the south of Hunan province were principally controlled by tectonic, most of which were associated with granitic activities, hosted in certain geological stratigraphy horizons. All the fractures and magmatic bodies show distinct features of gravitational-magnetic field. It's summarized in this paper that there are two gravitational-magnetic field features of two types of different genetic granitoids series, and that the regional aeromagnetic anomolies are mainly related to four large batholiths in Qitianlin-Qiansan area. And it is deduced that the local anomolies are associated with high level magmatic rock bodies or zones. By and large, eleven promising areas for prospecting are proposed.
