An importance of the geological investigations in Kavaklıdere geothermal field (Turkey)

Original Article

Abstract

The geological characteristics of a Kavaklıdere geothermal field is of particular importance during the evaluation of a geothermal prospect. The field covers a 126 km2 area between Alaşehir and Salihli districts in Manisa province, Turkey. The field was mapped geologically at the scale of 1/25.000 in order to determine heat source(s) and various characteristics of rock sequences, such as their lithofacies, thickness, contact relationships, stratigraphy, and whether there are cap and/or reservoir rocks exposed in and adjacent to the field. In the Kavaklıdere geothermal field, 38 fault planes in total were measured, including 7 detachment faults, 15 high-angle normal faults, 2 low-angle normal faults and 13 shear fractures/strike-slip faults (scissor faults). Temperatures in the Kavaklıdere geothermal field range from 188 to 287 °C. Permeability in the reservoir consists of a network of fractures in hard metamorphic rocks a short distance above a granitic intrusion. In this study, in the Kavaklıdere geothermal field about the formation of geothermal model, the evaluations are made about the reservoirs, cap rock, recharge, heat source and prepared geothermal model.
