Abstract

The determination of the lower edges of magnetized bodies in the Earth's crust is a complex geophysical problem, although these values can be estimated by using geothermal data. An analysis of the temperature regime and location of the lower edges of magnetized bodies has been carried out for the geosynclinal region of the southern Caucasus and the area joining the ancient platform with the Arabian Shield in Israel. Geothermal calculations for Israel have been performed for three models of the thermal regime for the Earth's crust and upper mantle. The process of ultrabasic rock serpentinization is accompanied by the transformation of iron suboxide to iron oxide. Both these processes run under identical thermodynamic conditions within an average temperature interval of 200°-400°C. The Curie surface controls the position of lower edges only in fault zones where oxidation conditions hold up to great depths.
