| Abstract |
The Canakkale-Yenice-Hidirlar geothermal area is in the vicinity of the Hidirlar village, Yenice country, Canakkale city in Turkey. In the area, there are three hot water springs, their temperatures ranging from 40 to 87 0C and their total flow is between 30 and 40 l/sec, geological and geophysical resistivity studies have been carried out in the area. The fluid to be obtained in the area can be used in not only thermal tourism but especially in greenhouse and household heating as well. Geologically, the Karakaya Formation of lower Triassic age overlies the Kardağ group metamorpichs at the base. The Oligo-Miocene aged Eybek granodiorite unconformably overlies it. The lower Middle Miocene aged Hallaçlar volcanites are unconformably overlain by the Bigadic Formation precipitated in the lagoonal basin in Neogene, The Quaternary aged alluvion is the youngest unit in the area. The region is within the western extension of the North Anatolian Fault Zone and has been affected by recent tectonic actvities. The Kalkim graben has been formed, tectonic movements in NE-SW directions are currently active as a result of these movements, debris materials can be observed over the Neogene units in the northern part of the region. As a result of these studies, it is seems that in the investigated area that there are downfalls in steps from north to south and that they are cut by both vertical strike slip faults developed in horizontal and vertical directions to them. Hot water resources crop out in the northern part of the Kalkim graben and can be observed in 3 different points, the hot water resources are controlled by NE-SW directions of faults with secondary faults cutting them. No hot water resources were seen in the northern wing of the graben. It is thought that the available hot water resources in the investigated area originate from crack-fracture systems. It is estimated that the cover thickens towards the northern part of the resources and that the main reservoir may be under these levels. As a result of this study, drilling locations have been suggested at two different points. One of them has been drilled. |
