Make Use of Gravity Field to Research Mohe Basin Tectonic Framework

Based on the discrete cosine transform(DCT) of the gravity anomaly is data processing,inversion is of high precision and better stability.DCT will be based on the level of gravity anomaly first derivative,the first derivative vertical,single-density single interface abnormal inversion and Euler deconvolution methods used to Mohe Basin gravity anomalies in the data processing,the gravity field features Comprehensive analysis.The level of gravity anomaly first derivative extreme point,the vertical first derivative zero point and Euler deconvolution on the extension of 0 to 20 km fault tracking map inferred from 10 clear fracture.According to the inversion of the crystalline basement ups and downs and the distribution of fault zone,Mohe Basin will be divided into Daxinganling middle fault zone,Changying-pangu Depression zone,Changshan-yidong uplift zone and Yidong Depression zone.
