ABSTRACT
This sudy was prepared as a Master of Science thesis submitted to Science Institute of the
Suleyman Demirel University, Geological Engineering Department, General Geology Branch.
The investigation area is located between the Savköy, Direkli and Darıören villages around
Dereboğazı (Isparta). Aims of the study are to get a new geological map and to determine
lithological units by using satellite data. Field and laboratory works were carried out.
In the area, allochtonous and autochthonous units are seen. The basement autochtonous is the
Triassic-Jurassic aged Ispartaçay Formation. It consists of rhythmic deposits of chert,
radiolarite, plated limestone and turbiditic limestone. The Jurassic to Cretaceous aged Davras
Limestone has a lateral-vertical changes with the basement rocks. The Eocene aged Isparta
Formation including carbonates and clastics overlies uncomformably the Davras Limestone.
The Miocene sediments cover uncomformably older geological units. The Miocene
sediments from bottom to top are Karabayır Formation. It consists of basal conglomerates and
thick bedded reeifal limestone. The Güneyce Formation including rhythmic sandstone and
claystone and the Gökdere Formation comprasing limestone and terrestrial conglomerates are
also the geological units Miocene in age. The Gölcük Volcanics and Recent sediments are the
youngest units in the investigation area. The Isparta Ophiolitic Complex was separated as an
allochtonous unit in the area. All geological units were mapped and identified by using
satellite images, 1/25.000 in scale. Particularly, digital data were used for identifying and
interpreting of the indicated geological units.
New and different techniques were suggested and used for geological mapping on the satellite
images. Three dimensional analyzing , digital image processing, GPS using and different
technological methods are also possible on the mapping. For uploading to collected field data
on the satellite images, different methods have been suggested.
Geological units were correlated in the views of spectral values, topography, drainage system,
luminosity and vegetation cover by using digital layers. Landsat and Spot images give very
important results for petrographic, stratigraphic and tectonic interpretation. Using the satellite
images, especially identifying lithologic units and tectonic features interpretation of the
relationship between the units should be carried out by field work support.
