Abstract

Ground geophysical surveys in kimberlite bodies prospecting are carried out to evaluate prospects for anomalies identified by airborne geophysical surveys and select areas for confirmation drilling as well as at minor prospecting areas where airborne geophysical surveys are uneconomic. The main, internationally adopted compex of ground geophysical methods includes magnetic survey, electrical prospecting of various types and, in some cases, gravity prospecting. Magnetic survey and electrical prospecting activities are most efficient in kimberlite prospecting. In complex prospecting environments,
transient process method is most informative.
