Application Effect of High-precision Gravity and Magnetic Measurements with the Scale of 1∶50000 in Qixia-Penglai Bronze Polymetallic Metallogenic Predication Area

摘要:

阐述了1∶5万高精度重磁测量在栖霞蓬莱金铜多金属成矿预测区的应用效果，高精度重力测量对老、中、新地层反映明显，表现出较好的对应关系。根据该次高精度重磁资料推测了测区内的构造及中生代侵入岩体的分布，圈定了成矿远景区，显示出高精度重磁测量在成矿预测区较好的地质找矿效果，为该区下一步金铜多金属找矿工作提供了较好的依据。

Abstract:

In this paper, application effects of high-precision gravity and magnetic measurements with the scale of 1∶50000 in Qixia-Penglai bronze polymetallic metallogenic prediction area have been introduced. High-precision gravity measurements can refeclt old, medium and new strata obviously, and show a good correlation relationship. According to this precision gravity and magnetic data, structures in survey area and the distribution of Mesozoic intrusions have been concluded, and mineralization prospect has been delineated. It is showed that precision gravity and magnetic measurements has a good geological prospecting effect in ore-forming predication area. It will provide a good basis for prospecting work in the future.
