Abstract

Abstract:

As a new electromagnetic exploration method，multi-channel transient electromagnetic method（M-TEM） distinguishes itself from the electromagnetic family by its high resolution and large detection depth.The peak times of cross correlation function between transmitting current and received voltage give a new pseudo cross-section profile of apparent resistivity，which can reflect underground geoeletric structure very well.The field survey and data processing of M-TEM was discussed.In addition，a single-line M-TEM survey was conducted in Baertaolegai-Fuxingmen silver-lead-zinc polymetallic ore investigation zone.In data acquisition，it is deployed that a 240 m or 480 m inline dipole galvanic current source and 180 inline potential receivers with length of 60 m along 10.8 km survey line.The resulting pseudo cross section of M-TEM apparent resistivity is consistent with the borehole result.It is considered that M-TEM has a great application potential in future metal mineral exploration.

Key words: multi-channel transient electromagnetic （M-TEM） , Wiener filtering, cross correlation, earth impulse response, green function, metal mineral exploration, Da Hinggan Mountains, Baertaolegai-Fuxingtun
