The geophysical method to be applied for gold exploration will vastly depend on geological inputs defining nature of mineralization which will also include other minerals associated to decide the geophysiclal methods keeping in view interferences caused by such association.
GEOPHYSICS FOR MINERAL EXPLORATION 1.0 INTRODUCTION The purpose of carrying out geophysical surveys is to find out something about the rocks in the survey area. Geophysical methods all depend on measuring a physical property of rocks. There are only a

The word “geophysics” in oil exploration is often used synonymously with “seismic”, overlooking many other fruitful techniques. In mineral exploration and engineering projects, applicability of seismic imaging is often limited and other geophysical methods take the front seat.
• Exploration in geophysics is an applied branch of geophysics, which uses physical methods (such as seismic, gravitational, magnetic, electrical and electromagnetic) at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties.

Advances in Geophysical Technology for VMS Exploration Boivin, M.  _____ 1. MB Geosolutions, Quebec City, Quebec, Canada ABSTRACT Over the last decade, new geophysical technologies for mining exploration were developed and are directly applicable for VMS exploration.
Mineral Exploration Applications Magnetics are the most commonly used geophysical method for gold, diamond, platinum group metals and base metal exploration. Select any type of gold project, (quartz vein, sulphide-hosted, shear zone, alluvial or placer) and you will see magnetic reconnaissance maps or detailed maps for drilling.

The geophysical anomalies mapped are then studied by the geologist who overlays geochemical and other geophysical data. The geologist looks for coincident anomalies which can then be followed up with field work and drilling. Iron oxide-copper-gold (IOCG) deposits can be identified quite successfully using the gravity survey method. These ...
Geophysical and geochemical methods therefore have important roles to play in any exploration programme. A wide variety of geophysical methods has been used for the Department of Industry Mineral Reconnaissance Programme and the selection of the method has been determined mainly by
