Geophysical Electromagnetic Survey Equipment CSEM/ CSAMT Controlled-source audio-frequency magnetotellurics (CSAMT) groundwater Geothermal exploration                                                                                           Controlled-source Audio-frequency Magnetotellurics (CSAMT) is a type of CSEM surveying in which the transmitter is placed in the far field from the receiver. Early in the development of the method this was done to simplify modeling the data using mathematics and software originally written for modeling natural-source (rather than controlled-source) MT data. Instrument introductionGD-4 electromagnetic survey equipment is based on the mature magnetotelluric sounding theory, using random signal processing technology, a wide-band magnetotellurometer that integrates high-frequency magnetotelluric (HMT), audio magnetotelluric (AMT), and magnetotelluric (MT or LMT). Application areasGeophysical Electromagnetic Survey Equipment CSEM/ CSAMT Controlled-source audio-frequency magnetotellurics (CSAMT) groundwater Geothermal exploration1.Exploration of metal and non-metallic mineral resources;2.Urban, highway, railway and power engineering geological exploration (karst, fault fracture zone, landslide body, etc.);3.soil, garbage station environmental monitoring, etc.;4. Hydrogeological exploration such as groundwater and reservoir dam foundation.                                                                                 Features and functionsGeophysical Electromagnetic Survey Equipment CSEM/ CSAMT Controlled-source audio-frequency magnetotellurics (CSAMT) groundwater Geothermal exploration1.Mixed mode of natural source and artificial source ─ ─ Applying the principle of magnetotelluric sounding, it can carry out the magnetotelluric sounding of natural sources, or the magnetotelluric sounding of artificial sources, or a mixture of the two.2.
