TI  - Investigating edge detection, Curie point depth, and heat flow using EMAG2 magnetic and EGM08 gravity data in the northern part of Eastern Anatolia, Turkey
AB  - The edge detection, the Curie point depths (CPDs), and the heat flow in the northern part of Eastern Anatolia were examinedusing EMAG2 magnetic and EGM08 Bouguer gravity data. Edge detection methods are extensively employed to delineate the edgesof sources using potential field data. In the study area, the tilt angle, total horizontal derivative, theta map, and 3D Euler deconvolutionmethods were used to delineate the subsurface geology and heterogeneity. The 3D Euler deconvolution method was carried out todetermine the depth of the subsurface magnetic and gravity anomalies. The Euler depth solutions show that the depths range from 0to 15 km for the Bouguer gravity anomalies, while the depths vary from 0 to 16 km for the magnetic anomalies. In this study area, theCPD values vary between 15.7 km and 18.6 km. For a thermal conductivity of 2.5 W m–1 K–1, the heat flow values were determined tobe between 75 and 95 mW m–2. A plot of CPDs versus heat flow values revealed an exponential correlation between heat flow and CPDvalues. A good relationship was detected between the CPDs and the heat flow values.
