“…El-Nabi (2012) suggested also that the window size of 60 km × 60 km was necessary to obtain the Curie point estimate from magnetic data. Ateş et al (2005) calculated the average CPD as 15.36 km in central Anatolia. Therefore, the study area was divided into 3 overlapping blocks with dimensions 60 km × 60 km.…”

“…In central Anatolia, some gravity, magnetic, and seismological studies have been performed to interpret the crustal structure (Saunders et al, 1998;Ateş et al, 1999Ateş et al, , 2005Aydın et al, 2005;Çakır and Erduran, 2011;Tezel et al, 2013;Kind et al, 2015). Tezel et al (2013) determined the crustal thickness in the central Anatolia to be 31-38 km determined by receiver function.…”

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.

“…The same method has been applied with success to several regions, such as Nevada (BLAKELY, 1988), East and Southeast Asia (TANAKA et al, 1999), Western Argentina (RUIZ and INTROCASO, 2004), Japan (TANAKA and ISHIKAWA, 2005), Turkey (DOLMAZ et al, 2005;AYDIN et al, 2005;ATES et al, 2005;BEKTAS et al, 2007), Slovakia (ROZIMANT et al, 2009) and California (ROSS et al, 2006). Although this is a convenient indirect method for inferring the thermal structure of continental crust, it has several drawbacks.…”

We investigate the regional thermal structure of the crust in Mexico using Curie Point Depth (CPD) estimates. The top and bottom of the magnetized crust were calculated using the power-density spectra of the total magnetic field from the freely available ''Magnetic Anomaly Map of North America''. We applied this method to estimate the regional crustal thermal structure in overlapping square windows of 2°9 2°. The CPD estimates range between 10 and 40 km and show several regions of relatively shallow and deep magnetic sources, with a general inverse correlation with measured heat flow. A deep CPD region (20-30 km) is located in the fore-arc area where the subducting Cocos plate has a flat-slab geometry. This deep region is bound to the NW and SE by shallow CPD areas beneath the states of Michoacan (CPD = 12-16 km) and Oaxaca (CPD = *16 km), respectively. There is a good spatial correlation between this deep CPD area and two main fracture zones located on the incoming Cocos plate (Orozco and O'Gorman fracture zones), suggesting that subduction plays an important role in setting apart different CPD provinces along the Mexican coast. Another deep CPD (16-32 km) area corresponds to the region where the Rivera plate subducts beneath Jalisco block. The Trans-Mexican Volcanic Belt is characterized by a decrease in Curie depths from west (16-20 km) to east (10-12 km). Finally, several deep CPD areas are situated in the back-arc region where old Mesozoic terrains are present. Our results suggest that the main control on the crust's regional thermal structure in the fore-arc and volcanic arc regions is due to the subduction of the Cocos and Rivera plates beneath Mexico.

The eastern Pontides orogenic belt is one of the most complex geodynamic settings in the Alpine-Himalayan belt due to the lack of systematical geological and geophysical data. In this study, 1D crustal structure and P-wave velocity distribution obtained from gravity modeling and seismological data in the area has been used for the development of the thermal model of the eastern Pontides orogenic belt. The computed temperature-depth profiles suggest a temperature of 590 ± 60°C at a Moho depth of 35 km indicates the presence of a brittle-ductile transition zone. This temperature value might be related to water in the subducted crust of the Tethys oceanic lithosphere. The Curie temperature depth value of 29 km, which may correspond to the crustal magma chambers, is found 5-7 km below the Moho depth. Surface heat flow density values vary from 66.5 and 104.7 mW m -2 . High mantle heat flow density value of 48 mW m -2 is obtained for the area should be related to melting of the lithospheric mantle caused by upwelling of asthenosphere.
