This study has been carried out in the topographic maps of Marmaris O19 a3d2
and partially in the Marmaris O19 a4-d1 where include Datça village and its near
surroundings in Muğla. Structural position of the investigated area that covers an
area of approximately 108 square km have been studied and also tectonostratigraphical
setting of Lycian nappes seen in the area are tried to be explained.
Lithostratigraphical units of the area are mainly made up of palaeotectonic
and neo-tectonic units that have subsequent (long) time gap each other. 7
lithostratigraphical units have been differentiated and mapped according to the
settlement of the tectono-stratigraphical units of the study area. These units from
bottom to the top as follow; Aptian-Albian age Marmaris peridotits (lower tectonic
slice); Toarcian-Late Creatceous age Göçgediği formation (middle tectonic slice);
and middle Triassic-Liassic age Kayaköy dolomites, late Jurassic-Lower
Maastrichtian age Orhaniye formation and late Senonian age Karaböğürtlen
formation (upper tectonic slice). Terrestrial and marine facies of Yıldırımlı formation
is of late Piacenzian age rests on the present palaeotectonic units with angular
unconformity. The youngest sediments of neo-tectonic units are Quaternary age
volcanics, slope deposits, beachs sediments and alluviums that rest on the Yıldırımlı
formation with angular unconformity. 9 differently oriented normal and dextral strike
slip faults have been observed and mapped within the investigated area. 1/25.000
scale detailed geological maps of the study area, generalized tectono-stratigraphical
section and three geological cross sections have been prepared with the data obtained
from the field studies.
