Deep Morphology and Connectivity Determination of Late Triassic Shuangdinggou and Xinling Rock in Qingchengzi, Eastern Liaoning

The late Triassic Outstanding and Xinling rock exposed adjacently and both belonged to late Triassic grannitic magmatic events in Qingchengzi mining area of Liaoning-Jilin rift belt. The deep boundaries were determined and deep distribution morphology were explored. Hence, we found out the deep connectivity condition between the two rock. Applying the gravity and magnetic anomaly datas of 1:200000 scales in Dan dong area, and the processing interpretation of high-precision gravity magnetic survey datas and MT measured non seismic geophysical datas of two comprehensive profiles, simultaneously combined with measured density data of the samples, we performed comprehensive analysis on the basis of various anomalous signs , constrained rock morphology to control the profile and selected reasonable inversion parameters to carry out the gravity and magnetotelluric sounding joint inversion constraint by basic geological information. On basis of the work above, the deep geological structure inversion of 4 auxiliary profiles were completed, the rock spatial distribution geometrical morphology were found out, besides, the connectivity of the concealed rock underground between the two rock were determined. These provide reference for studying spatial distribution, ways the rock occurred and relationship between the mineral distribution and spatial distribution.
