ABSTRACT:
In the study area located in the southwest part of Konya Dessert, shallow and pelagic deposits takes place and forms the autochthonous base of the area related with Jurassic‐Late Cretaceous age Bolkardağı tectonic unit. Basic volcanics included in ophiolitic melange related with Bozkır tectonic unit, which completed its formation by Senonian and was located after Maestrihtian, comes onto the autochthonous base with a tectonic contact. Ophiolitic unit is covered with unconformity by Late Miocene‐Early Pliocene age alluvial fan and lacustrine carbonates. Late Pliocene‐Pleistocene age alluvial fan and talus sediments cover all units older than themselves with unconformity. The youngest litologies are Holocene age alluviums.
In the Early Middle Alpine orogeny period, the area was deformed due to hard compression strains. In this period, Ophiolitic nappe was located in the area after the rocks belonging to autochthonous base had been folded and broken. In the Late Alpine orogeny, closed basins controlled by the gravity faults were formed by the tension strains. These Late Miocene‐Early Pliocene age basin sediments that come with unconformity on autochthonous and allochthonous units are continental type molaces. These molaces and younger talus and alluvium fan covering them with unconformity form the Upper Miocene‐ Quaternary rocks in neoautochthonous location.
