Enhanced 3D velocity structure, seismicity relocation and basement characterization of Changning shale gas and salt mining regions in Sichuan Basin

This repository contains the datasets and results of the joint inversion-based Vp/Vs model consistency constrained double difference seismic tomography carried out for the manuscript titled “Enhanced 3D velocity structure, seismicity relocation and basement characterization of Changning shale gas and salt mining regions in Sichuan Basin.” Included are the following:   catalog earthquake information (CX_event.dat), relocated events after inversion (CX_tomoDDMC.reloc), inverted Vp model (CX_Vpmodel.dat), inverted Vs model (CX_Vsmodel.dat) and inverted Vp/Vs model (CX_VpVsmodel.dat). Please consult the manual for tomoDD by Zhang and Thurber (2003) for detailed formats of these files.

本仓库收录了为题为《四川盆地长宁页岩气与盐矿开发区增强型三维速度结构、地震重定位及基底特征刻画》的学术稿件所开展的、基于联合反演且受Vp/Vs模型一致性约束的双差地震层析成像的数据集与反演结果。所包含的文件如下：地震目录信息文件（CX_event.dat）、反演后重定位事件文件（CX_tomoDDMC.reloc）、反演得到的Vp（纵波速度）模型文件（CX_Vpmodel.dat）、反演得到的Vs（横波速度）模型文件（CX_Vsmodel.dat）以及反演得到的Vp/Vs模型文件（CX_VpVsmodel.dat）。有关上述文件的详细格式，请参阅Zhang与Thurber于2003年发布的tomoDD工具手册。
