Abstract

Geophysical methods used in mineral exploration give satisfactory results in the determination of underground mineral deposit. Geophysical surveys aim that modeling possible changes in subsurface by using mathematical and physical correlations. The relationship arising from differences in phsical characteristics between the ore bed and wall rock is an important factor in determining method to be used on selection of the most suitable geophysical methods. Data collection is carried out by the use of electronic devices. Digital data are measured by a variety of geophysical devices. There are many geophysical methods such as gravity, electricity and electromagnetic which measure differences arising from underground geological variety. In this study, some of basic principles of geophysical methods used in mineral exploration are explained and examples are given to studies which are made.
