The Relationship between Heat Flow Regime and Active Tectonics Inferred from Seismological Data in Western Anatolia

Abstract

The hydro-chemical data sets of many hot springs in the Anatolia obtained from available reports of Mineral Research Institute (MTA) and literature are used to calculate terrestrial heat flow values around western Turkey. These data sets include surface temperature, conductivity, alkalinity, acidity, TDS, pH values, H2S, Ca, Cl, F, Fe, K, Mg, Mn, Na, NH3, SiO2, SO4 contents, their locations, usages and other relevant information. The silica heat flow interpretation technique is applied to available hot springs. For this purpose, quartz (silica) and Na-K-Ca geothermometer calculations were firstly made. The heat flow values then derived from silica geothermometer and were imaged on the seismological pattern over the western Anatolia. Several pictures showing qualitative relationships between heat flow regime and active tectonic inferred from seismological data were constructed for some focussed regions. Our interpretations indicate that heat regime in the western Anatolia is well associated with active tectonics.
