Geology of the Halitpaşa basin (the northern elevation Çaldağ), Manisa

The Late Cenozoic evolution of the eastern Aegean is dominated by widespread continental extension. The most prominent structures are E-W and NE-SW trending grabens and intervening horsts, while NW-SE and N-S trending faults form the other less important structures. This paper documents the results of recent geological mapping and structural and stratigraphical analysis from the Halitpaşa half graben, which forms the northwestern continuation of the Gediz Graben. Field evidence for a new NW-SE trending dextral wrench-dominated fault zone (here named the Halitpaşa transpression zone), which involved the thrusting of pre-Palaeogene basement onto Upper Miocene-Lower Pliocene sediments, is presented. The fault zone is correlated with the timing of a major unconformity that separates Upper Miocene-Lower Pliocene lacustrine sediments (Develi and Halitpaşa formations) from overlying late Early Pliocene, distal alluvial-fan sediments (Kızıldağ Formation, As a result of the kinematic analysis of NE-SW direction is seen as an expansion of the graben structure formed in Halitpaşa and Poets to associate with the extensional tectonics of the basin will be an appropriate decision.
