Özet

Important volcanic occurrences such as a sub-volcanic stock. caldera. volcano cones. circular. semicircular and elliptical morphologic structures have been identified in the Golcuk Crater Lake district and surrounding area. SW Turkey. Our satellite image analysis shows that the volcanic activity occurred during different volcanic phases. Maps of lineaments and geology of the region were prepared using colors. drainage patterns, textural features. vegetation cover and morphological forms as interpretation parameters. In addition, the major fracture directions of the region were detected from lineament analysis as trending NE, N, and NW. The relationship of Pliocene Golcuk volcanism with tectonism was defined and these data are interpreted. The satellite image reveals that the volcanic structures and the Golcuk Crater generally occur at the intersections of different lineaments, where the number of lineaments increases. Lineament analysis on Landsat satellite images is a useful tool for detecting volcanic regions. alteration and mineralization zones. (c) 2005 Elsevier Ltd. All rights reserved.
