We hypothesize that the Biga kaolin deposits are parts of the similar hydrothermal systems and epithermal mineralization of Biga and Aegean Regions show compatibility with the similar crustal extensional regime of Rio Grande Rift, USA. Moreover, their age relations, genetic occurrences (hypogene vs supergene), genesis of calc-alkaline volcanism, isotopic characterization of mineral assemblages and fluid types in a space-time context, aqueous H2S - SO42- isotopic equilibrium and isotopic exchange rates are not well-known. The foregoing aspects will be tested in terms of field and mineralogical studies on alteration zones, REE and trace element geochemistry, Ar-Ar dating and stable isotopic composition. The study area is selected unique occurrences and extensive hydrothermal alterations associated with western-end branches of North Anatolian Fault zone and branches of major active Aegean tectonism and volcanism within the Neo-Tectonic system. Alternatively, acid-sulphate hydrothermal alterations from Japan, Philippines and New Zealand will be compared for the better understanding of fossil geothermal systems.
