Detection and discrimination of complex thrust and salt tectonics structures using field data and RASAT images around the Emirhan region (Sivas, Turkey) [Emirhan (Sivas) Civarinda Karmasik Bindirme ve Tuz Tektonigi Yapilarinin Arazi Verileri ve RASAT Görüntüleriyle Ortaya Çikarilmasi ve Ayrimi]

RASAT L2 visible and panchromatic images were used to detect both thrust and salt tectonics structures as a reliable geologic mapping tool in this research. As a geographical transition plateau between Inner and Eastern Anatolian region, Sivas Basin doesn't show hampering vegetation on geologic outcroppings for remote sensing analyses. This feature also allow healthy interpretation possibilities. Salt structures in Sivas Basin can be counted in worldwide well-known examples (e.g. La Popa Mexico, Great Kavir Iran and Axel Heiberg Canada) conveniently. In this research, a detailed geological map was prepared in the field. The results show that both of visual interpretations and digital image processing methods spectrally could provide healthy discrimination power between different rock lithologies. Image fusion method was contributed to reveal these subtle tectonic and geomorphologic evidences that developed in and between salt and clastic lithologies. In addition, specifically chosen Landsat ETM+ bands such as 5 and 7 images together with RASAT visible bands were also used to create RGB combinations for geological studies. © 2016 IEEE.
