Curie Point Depths and Heat Flow of Eastern Anatolia (Turkey)

Abstract

AbstractThe bottom of the magnetized crust determined from the spectral analysis of magnetic anomalies is generally interpreted as the level of the Curie point isotherm. The spectral analysis method to estimate the depth extent of magnetic sources was applied to the magnetic anomalies of Eastern Anatolia and compared with the tectonic regime and heat flow data in the region. The Curie point depth of eastern Anatolia ranges from 6 to 24 km. The computed Curie depths and the heat flow values derived by using Curie depths are consistent with the geological and the seismological findings of the region. Shallow Curie point depths and high heat flow values are seen between the Bitlis Suture Zone and the pontides. At the same time, this region might contain a thinner crust than expected.Keywords:: crustal thinningCurie point depthEastern Anatoliaheat flowspectral analysis ACKNOWLEDGMENTThe authors wish to thank Dr. Ekrem Zor, whose study they benefited from.FUNDINGThis study has been achieved under the scope of the Scientific and Technological Research Council of Turkey (TUBITAK) project (No. 101Y124) and Dokuz Eylül University, Scientific Research Projects (Project Code: 02.KB.FEN.084).Additional informationFundingThis study has been achieved under the scope of the Scientific and Technological Research Council of Turkey (TUBITAK) project (No. 101Y124) and Dokuz Eylül University, Scientific Research Projects (Project Code: 02.KB.FEN.084).
