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.本数据集仓库包含为研究论文《四川盆地长宁页岩气与盐矿区增强型三维速度结构、地震重定位及基底特征刻画》所开展的、基于纵横波速度比（Vp/Vs）模型一致性约束的联合反演双差地震层析成像的相关数据集与计算结果。其中涵盖以下文件：地震目录信息（CX_event.dat）、反演后重定位的地震事件（CX_tomoDDMC.reloc）、反演得到的纵波（Vp）速度模型（CX_Vpmodel.dat）、反演得到的横波（Vs）速度模型（CX_Vsmodel.dat）以及反演得到的Vp/Vs模型（CX_VpVsmodel.dat）。请参考Zhang与Thurber于2003年发布的tomoDD程序手册，以获取上述文件的详细格式规范。
