Abstract

 Turkey is located on the orogenic, active,
tectonic Mediterranean belt where frequently young volcanic activities are
observed during the Alpin orogenic phase strong fracturing, tectonics, magma
uprise followed by magma chamber locating in the earth crust played important
role in the existence of the geothermal systems. Geo- physical surveys have
very important role in the exploration of geothermal fields in Turkey. Very
impotant information is obtained about the location depth and formation of the
re servoir systems by applying several basic geophysical methods according to
the fields characteristics. Since the electrical resistivity values decrease in
the rock formation incon- tact with saline water and hot water in a geothermal
field electrical resistivity methods are widely used in Turkey too. For
reconnaissance of the location and the dimensions of shallow geothermal
reservoirs shallow temperature gradient method which is directly applicable
like electrical resistivity method is proven to be a fast and cheap method
accor- ding to the studies carried on in the field. With the equipment
available in Turkey geophysical surveys carried out up till date makes it
possible to get information from a limited depth which is in the order of few
kilometers. Therefore no geophysical data is obtained dealing with the neat
source which is much deeper. Application of geophysical surveying methods such
as heat flow and' much deeper magnetotelluric methods is necessary for both
improving the existing proven geothermal system and also exploration of
consealed geothermal systems with no surface manifestation like hydro- thermally
altered rocks, hot spring ete.
