Bayatcık Jeotermal Sahasında (Afyonkarahisar) Yer Alan Bayatcık-1 Kuyusunun Jeolojisi ve Alterasyon Mineralojisi

Abstract

Bayatçık geothermal field is located 7 km northwest of the Afyonkarahisar. The aim of this study is to determine the borehole geology and hydrothermal alteration mineralogy of Bayatçik-1 well, was drilled in 2013. The well is 925 meters deep. The types of rock that were encountered in this well were alluvium, volcanic and sedimentary sections of the Köprülü volcanosedimanter sequence, basal conglomerate, marble and schist sections. The cover rocks of the geothermal system consisting of volcanic and sedimentary rocks were drilled in the first 528m. Basal conglomerate was observed in 528-558 m level. Marble unit (Mrb1), which is the reservoir rock of the geothermal system at depths of 558-574 m, micaschist (Sch1) between 574-622 m, marble-2 between 622-746 m (Mrb2), micaschist-2 (Sch2) between 746-830 m, marble-3 between 830-890 m (Mrb3) and finally at depths of 890-920 m is a schist unit which acts as the impermeable basement rock of the system. The analyzes such as stereo and polarizing light microscope, x-ray diffractometer (XRD) and scanning electron microscope (SEM) were applied to the clastic samples taken at 2m intervals from Bayatçik-1 well. The result of the study is aimed to reveal the development of the geothermal system in the Bayatcık region by the differences in the hydrothermal alteration mineralogy of the samples. In the study, mineralogical-petrographical data were obtained with the presence of smectite, illite and kaolinite minerals formed at a temperature lower than 200 o C.

Investigation of the Use of Kütahya Region Kaolin in Wall Tiles

“…It requires the research and development of quality raw materials resources, which are depleted day by day, the discovery of new raw material areas and the more efficient use of existing raw materilas resources. Additionally, the increasing need for raw materials suitable for producing this material [1,2].…”
