Introduction
The area studied is located in the Soulheast of Analolia occupied
with 7 towns of Adiyaman. Diyarbakir, Gazianlep. Mavas. Mavdin. Siivl.
Urfa and bounded by the latitudes 369-399 N and the longitudes 369-439 E.
The area is approximately 90.000 square kilomelers. and surrounded by
the political boundary of Syria in [he soulh. The vi ver Euphrales. (he
longest river of the Middle East. flows through the area transversing all
the way from north to south. A subdued topography with gently slopes
prevails in the east. whereas a rugged topography of Eastern Taurus and
Amanos mountains can be seen in the west.
Southeastevn Turkey is a continuation of the Arabian peninsula
extending to the northwest. The region is a conspicous sedimentary basin
containing the prolific oil fields of the Middle East. This part of lhe
country has been the center of exploration activities during the past 20
years. À short review of the geology. the results of drilled wells and the
production data of the oil fields would indicate that perhaps no major oil
field in the Middle East sense will be found in this region. However there
ave many reasons for believing that more oil. even of good quality and
quantily will be discovered provided the search continues.
Instrumentation
First. the index of Landsat images of the area under sludy was
reviewed and three photographs were selected. The pholographs used in
this investigation were laken by Landsal spacecraft in August 1975. The
approximate scale of the images is 1/1.000.000. Each frame covers an
area of 185 km x 185 km. The photographs employed in this study consist
of a four channel (band) optical scanner. Four spectral bands are as
follows: band 4 records blue-green light (0.5-0.6 microns) band 5 red
light (0.6-0.7 microns). bands 6 and 7 infrared light (0.7-0.8 and
0.8-1.1 microns) respectively. The paper prints of 7"x7" black and white
were obtained. The quality of the images is quite good.
Procedures
Asetate papers were laid doun on the photographs and annotations
were traced on these papers. The photographs were examined under the
hand lens. The findings were correlated with geological literature and
maps and even conventional aiv photographs were used. The geological
analyses weve carried out with the stratigraphical and structural
investigations. The emphasis was based on the differentiations of the
lithologies and the structural features.
