This study is aimed to perform digital geologic mapping and ASTER image analysis around southeastern
part of the Sivas Tertiary Basin. The interest area is located at the intersection of ENE-WSW oriented
Deliler Thrust Belt and Tecer Fault Zone. Ophiolithic rocks which were belonging to Inner Tauride
Ocean Suture belt were outcropped in a vast region. This region also forms the northern boundary of the
Menderes-Tauride platform. Tectonostratigraphy of the region is represented by two different sedimentary
sequences separated by Deliler Fault Zone. While a thick cover of Oligocene-Miocene continental unit was
observed on the southern section of Deliler Fault Zone, Lower-Middle Eocene marine, Oligocene gypsum
and Lower Miocene marine sediments were outcropped on the northern part of this belt. Late Miocene
continental deposits were folded while Plio-Quaternary fluvial sediments were observed horizontally
along the Deliler Thrust Zone. Within the context of this study, interested region was mapped digitally
using tablet pc and ArcPad software. Using this software, areas of outcropping units, linear geologic map
elements like faults and fold axes were recorded digitally during field studies and some database queries
such as formation name, age, and lithologies were determined in terms of saving time and digitization
efforts. Additionally, a number of image processing efforts were applied to 14 channels ASTER image of
the region to highlight geological features such as lithological boundaries and structural components.
Thus, a detailed digital geologic map was formed at the end of this search. Furthermore, a number of
image processing studies were acquired supporting geological mapping at field.
