State‐of‐the‐art geophysics for metal exploration

Abstract

The new discovery of the economical metal deposit is getting more difficult year by year because the unexplored areas tend to be more remote areas than ever, and the metal prospective zones are deepening in the recent decades. Therefore, the advent of the state‐of‐the‐art or advanced geophysics technology to peer the deeper parts of the ground with higher accuracy and spatial resolution has been aspired in metal exploration industry. The author reports and introduces the drone‐based magnetic survey, the three‐dimensional time‐domain IP inversion algorithm using Cole–Cole parameter, the time domain electromagnetic method using superconducting quantum interference device (SQUID), and passive seismic survey as the state‐of‐the‐art or advanced geophysics technology for metal exploration.
