Magnetotelurica
WebINTRODUCTION Controlled source audio-frequency magnetotellurics (CSAMT) is a frequency-domain electromagnetic sounding technique which uses a fixed grounded dipole or horizontal loop as an artificial signal source. CSAMT is similar to the natural-source magnetotellurics (MT) and audio-frequency magnetotellurics (AMT) techniques; the chief … WebFor our study, we conducted alluvial deposits from the Lanyang River were laid over the audio magnetotelluric (AMT) surveys at the western part Paleogene rock basement, …
