Abstract:

 

This paper proposes an interpretation of the Bouguer gravity and magnetic anomaly map of the Yozgat Batholith and its surrounding area (north central Anatolia) for determination of crustal and geothermal structures. In the study area, the Moho and Conrad depths based on a relationship between Bouguer gravity anomaly and seismically determined crustal thickness were estimated as 34-39 km and 19.5-21.5 km, respectively. The crustal thickness of the study area increases from west to east. The estimated Curie point depths in the study area by means of spectral analysis of the magnetic data vary between 10.4 and 19.5 km. The shallow depths indicate that the magnetization is restricted to the upper crust in the study area. In addition, the heat flow values calculated for a thermal conductivity of 2.7 W m-1 K-1 range from about 80 to 150 mWm-2. The shallow velocity structures in central Anatolia are consistent with the estimated high heat flow values in the upper crust and associated with comparatively high negative Bouguer gravity anomalies.
