雅鲁藏布江中下游沉积物地震探测数据（2020-2025）

本数据集包含2020-2025年开展的雅鲁藏布江中下游沉积物地震探测野外工作获得的人工源地震数据。地震数据主要通过野外实地采集、测量获得，数据采集位置主要位于雅鲁藏布江中下游的米林县境内。地震数据整体质量较好，反射波、面波、直达波清晰。本套地震数据可以通过反射波叠加，初至层析成像，面波反演等方法进行处理，获得松散沉积物的地震成像结果。通过反射地震剖面、速度结构剖面等信息，可以划分雅鲁藏布江中下游地表以下沉积物的沉积结构，服务于沉积地质等科学研究和工程建设。

This dataset contains artificial-source seismic data acquired during field seismic surveys for sediment detection in the middle and lower reaches of the Yarlung Zangbo River, conducted between 2020 and 2025. The seismic data were mainly obtained through field collection and measurement, with most acquisition sites located in Mainling County within the middle and lower reaches of the Yarlung Zangbo River. The overall quality of the seismic data is good, with clear reflected waves, surface waves, and direct waves. This set of seismic data can be processed via methods including reflection stacking, first-arrival tomography, and surface wave inversion to obtain seismic imaging results of unconsolidated sediments. Based on information such as reflection seismic profiles and velocity structure profiles, the subsurface sedimentary structure in the middle and lower reaches of the Yarlung Zangbo River can be delineated, serving scientific research such as sedimentary geology and engineering construction.
