To support the development of rapid geophysical detection instruments for barrier deposits, a comprehensive geophysical survey was conducted on the Tangjiashan barrier deposit, including the following contents:
(1) CSAMT test data acquisition: A self-developed magnetotelluric system was employed, and CSAMT data from 14 measuring points within this area were collected, which was used to test the detection range, detection accuracy and operating reliability of the magnetotelluric system.
(2) Ground Penetrating Radar (GPR) data acquisition: A CO1760-type GPR from ImpulseRadar of Sweden was adopted. Five survey lines were arranged (Survey Line 1: 103.25 m in total length, Survey Line 2: 48.8 m, Survey Line 3: 53.5 m, Survey Line 4: 57 m, Survey Line 5: 95.3 m), which was used to test the detection range, detection accuracy and operating reliability of the GPR.
(3) High-density resistivity data acquisition: An EDJD-3 multi-functional digital DC resistivity instrument from Chongqing Dingfeng Company was used. The Wenner array and dipole-dipole array were applied, with 168 electrodes arranged at an electrode spacing of 2 m, and the total length of the survey line was 334 m. A total of 4519 datasets were collected, which was used to test the detection range, detection accuracy and operating reliability of the high-density resistivity method.
(4) Transient Electromagnetic Method (TEM) data acquisition: An EATEM-2 transient electromagnetic instrument from Chongqing Dingfeng Company was utilized, paired with a self-developed variable-turns transceiver-integrated TEM coil. 211 measuring points were arranged (56 points on Line L1, 79 points on Line L2, 76 points on Line L3), which was used to test the detection range, detection accuracy and operating reliability of the self-developed TEM coil.
(5) Natural-source surface wave data acquisition: A SDZ-2448A digital engineering seismograph from Chongqing Dingfeng Company was employed. 6 measuring points were arranged to form one survey profile, which was used to test the detection range, detection accuracy and operating reliability of the natural-source surface wave method.
