The study area is situated 3 km NE of Omerbeyli located 12 km W of province capital of Aydin in western Anatolia, Turkey. Here, an exploration, production and reinjection well with a depth of approximately 2.200 m has been drilled. In this well, we have collected 38 samples as rock fragments, in order to investigate hydrothermal alteration by x-ray diffraction and microscopical methods. In this geothermal area, the hydrothermal alteration mineralogy depends upon (i) temperature of geothermal system, (ii) pressure of the system, (iii) type of the rocks in reservoir, (iv) permeability of the reservoir rocks, (v) geochemical composition of the reservoir rocks and (vi) stability of the minerals of reservoir rocks. There is a close relationship between geothermal system and hydrothermal alteration. With respect to this relationship, the monitoring of geothermal systems can be ensured by the parameters such as temperatures and hydrothermal alteration zones providing that the hydrothermal alteration mineralogy has been investigated particularly. Therefore, the hydrothermal alteration mineralogy of the exploration, production and reinjection well with a depth of approximately 2.200 m in Omerbeyli has been revealed. (C) 2017 The Authors.
