Prediction of the distribution in eastern Shizhu aulacogen using gravity-seismic formation separation
The existence of Sinian-Cambrian rift troughs in the east of Shizhu has been confirmed by seismic data,but the distribution characteristics of these troughs cannot be accurately described due to the limitations of the data.Through the analysis and study of a large number of measured rock samples and drilling data,it is realized that the density of hydrochloric rock formation is high and the density of clastic rock formation is low in Shizhu area,and there is a certain density difference between different formations,it is a good physical property founda-tion for studying deep structure by gravity data.Therefore,gravity exploration has been carried out in Shizhu area,and the distribution characteristics of Sinian-Cambrian rift troughs and deep faults in the east of Shizhu area have been determined by gravity-seismic combined delamination inversion technique.
