Geophysical exploration for gold SpringerLink

The world-wide interest in gold that has characterized mineral exploration in the 1980s has had a profound effect on the focus and style of geophysical prospecting. In the 1950s and 1960s, direct detection methods (chiefly airborne and ground electromagnetics (EM)) were applied widely in the search for massive sulphide-hosted base-metal

Geophysical exploration for gold A review: Exploration

2018-12-6  Geophysical methods have been important in the search for gold in the Witwatersrand Basin of South Africa (magnetic, gravity and even seismic reflection methods), various areas of Canada (e.g. the Abitibi greenstone belt; magnetic, EM and IP surveys), and to a smaller extent in Australia (e.g. Tennants Creek, NT and Water Tank Hill, WA).

Models and Exploration Methods for Major Gold Deposit

2015-10-24  Selection of the appropriate exploration methods must be dictated by the characteristics of the targeted model, its geologic setting, and the surficial environment. Both greenfield and brownfield exploration contributed to the discovery of major gold deposits (>2.5 moz Au) in the last decade but the discovery rates have declined significantly.

Geophysical exploration for epithermal gold deposits

Abstract Epithermal gold deposits are highly variable in form, ranging from thin quartz veins to large disseminated deposits, and are located in a variety of geological environments. Consequently, they exhibit a wide range of geophysical signatures. Hydrothermal alteration accompanying these deposits causes pronounced changes in the physical properties of the rocks.
