چکیده

in this paper an indirect method is presented to detect potential geothermal sites in kerman province, southeast iran. geothermal heat flux is one of the main parameters to be investigated in geothermal exploration programs. however, few direct heat flux measurements are available for iran. given the proved relation between curie depths and heat flux, magnetic data can be used to calculate the curie depths in the areas where few or no direct heat flow measurements are available. the method presented here uses an iterative forward modeling approach to calculate the curie depth in kerman province. it has used the satellite magnetic crustal field model of mf5 obtained from champ mission. the equivalent source magnetic dipole method was used to estimate the magnetic crustal thickness from the observed induced field. the obtained curie map reveals an area with very low curie depth in the southeast kerman. the area may be considered as a potential geothermal site. geological evidence confirmed our findings for the probability of a geothermal site in the area.

Geothermal Exploration Methods

A geothermal reservoir causes inhomogeneity in the physical properties of the subsurface geology due to the high changes in temperature. These physical properties can be ob‐ served by means of varying anomalies from geophysical observations from the surface. These physical properties include electrical conductivity, rock density, magnetic suscepti‐ bility, rock elasticity, and, finally, the tem...

Determining fractal parameter and depth of magnetic sources for ardabil geothermal area using aeromagnetic data by de-fractal approach

The Ardabil geothermal area is located in the northwest of Iran, which hosts several hot springs. It is situated mostly around the Sabalan Mountain. The Sabalan geothermal area is now under investigation for the geothermal electric power generation. It is characterized by its high thermal gradient and high heat flow. In this study, our aim is to determine the fractal parameter and top and botto...

Application of Geochemical Methods in Geothermal Exploration

Subsurface waters have been classified into meteoric water, ocean water, evolved connate water, magmatic water and juvenile water. Geothermal water is mostly meteoric and oceanic water although andesitic waters near subduction areas often contain significant proportions of evolved connate and magmatic waters. Geothermal waters have been classified with respect to their anion and cation contents...

Natural State Model of the Nesjavellir Geothermal Field, Iceland

The Nesjavellir geothermal system in southern Iceland is very complex from both a thermal and hydrologic point of view. There are large pressure and temperature gradients in the wellfield and zones with drastically different pressure potentials. Thus, natural fluid flow is substantial in the system and flow patterns are complex. We have developed a twedimensional natural state model for the Nes...
