The field survey of 15 MT measuring points in Xianshuihe fault zone has been completed in this field observation. After subsequent integration with some old data sets, it is used to study the three-dimensional electrical structure of Daofu Shimian section of Xianshuihe fault zone. For the mtu-5a instrument used in this field observation, the recording time of each measuring point exceeds 40 hours, and each measuring point contains a TBL file, which is used to record the electrode distance, data saturation points and other information of field measurement, as well as three time series files. The file suffixes are Ts3, ts4 and ts5 respectively. Ssmt2000 software is used for data post-processing, which has reliable data quality and can be used to study the three-dimensional electrical structure of Xianshuihe fault zone.

File naming and required software

File name: the name of the measuring point file xsh01a, with the suffix TBL: the TBL file representing the xsh01 point. The three files with the suffix Ts3, ts4 and ts5 correspond to the time series of different frequency bands of the point respectively. Xsh01-xsh15 correspond to the names of 15 measuring points respectively.
Data reading method: after data post-processing under ssmt2000 software, power spectrum files such as apparent resistivity and phase can be output.
