The Liaodong-Jinnan metallogenic belt is a famous metallogenic belt in China.The mineral resources in the region are rich in mineral resources.There are famous metal non-metallic deposits such as Anshan iron ore,Fushun red transmite copper mine,Qingcheng Zi lead zinc mine,Baiyun gold mine and Huadian gold mine,which have been found huge reserves,but with the exploitation of mineral resources,many minerals are on the verge of exhaustion of resources.So the deep prospecting pressure in this area is huge.In the deep prospecting work,we should first study the characteristics of the deep tectonic environment,including the distribution of deep faults,the distribution of block bodies and the fluctuation of the interface,so as to better guide the prospecting work.In view of the needs of the deep metallogenic environment research in the southern Jinan metallogenic belt in Liaodong,the regional gravity and magnetic data have been collected.On the basis of the results of the basic geological survey,the characteristics of the regional deep tectonic environment and energy exchange are analyzed by the characteristics of the gravity and magnetic field,and the regional metallogenic environment is studied.The study of metallogenic environment in this paper focuses on the study of deep tectonic environment in the study area.First of all,we should fully grasp the regional geological data and conduct geophysical data processing on the basis of geological data.Secondly,the data processing and inversion of the bit field mainly adopts 3 methods,namely,the separation of the field by the method of wavelet transform(1)the oblique derivative method for the block boundary identification(3)inversion of the magnetic interface of the Parke method,and the data processing and inversion are carried out.According to the characteristics of the deep tectonic environment of the southern Liaodong metallogenic belt and the basic characteristics of the Liaoji Rift Valley,the characteristics of the deep tectonic environment of the southern Jinan metallogenic belt are clarified,and the energy exchange process between the deep and shallow parts is analyzed,and the basic data for the deep prospecting work are provided.
