Relationship Between Tectonic Lineaments and Springs North of Avanos (Central Anatolia, Turkey).

Abstract

The study area covers Avanos-Ozkonak and its surroundings north of Nevsehir province. An attempt was made to determine the relationship between tectonic lineaments and springs in the area. It was found that there is a close relationship between the location of springs and tectonic lineaments. In recent years, lineaments have been used in mineral exploration studies and geothermal areas. Remote sensing methods have also been used in this study. The relationship between tectonic lineaments (faults and fractures) and spring formations obtained from field studies and satellite-based studies was evaluated. Metamorphic rocks belonging to the Kirsehir massif and Paleocene-Middle Eocene aged units were subjected to polyphase deformation. As a result of these deformations, faults and cracks were formed. This situation has given aquifer properties to the rocks. At the same time, many springs were formed by faults and cracks. This study determined the relationship between 342 springs identified during field works and tectonic lineaments. Approximately 89% of the springs identified in the field were found to be located on the tectonic lineaments obtained from the satellite imagery. Some springs discharged from discontinuities on the formation boundaries.
