川滇地区岩石圈三维S波衰减模型

该数据集为利用基于全波形的伴随衰减成像方法反演获得的川滇周边地区的三维岩石圈S波Q值模型数据。首先向国家测震台网数据备份中心申请获得地震波形数据，利用采集的地震波形数据，按地震事件截取高信噪比的S波震相数据，并在去均值、去趋势、波形尖灭及滤波处理后提取S波振幅信息，最后利用波形伴随衰减成像方法对S波振幅数据进行反演，获得川滇地区的三维S波衰减模型。该模型数据集可用于进一步研究川滇地区岩石圈构造演化及青藏高原扩展等重要科学问题。

This dataset is a 3D lithospheric S-wave Q-value model of the surrounding regions of Sichuan and Yunnan, inverted using full-waveform-based adjoint attenuation imaging techniques. First, seismic waveform data was obtained via application to the National Seismic Network Data Backup Center. Next, high signal-to-noise ratio (SNR) S-wave phase data was extracted from the collected seismic waveforms by segmenting based on individual seismic events. Following processing steps including de-meaning, detrending, waveform tapering, and filtering, S-wave amplitude information was retrieved. Finally, inversion of the S-wave amplitude data using the adjoint attenuation imaging technique was conducted to generate the 3D S-wave attenuation model of the Sichuan-Yunnan region. This model dataset can be utilized for further research on key scientific issues such as lithospheric tectonic evolution and the expansion of the Tibetan Plateau in the Sichuan-Yunnan area.
