STRATIGRAPHIC FEATURES OF NEOGENE DEPOSITS OF DİLEKÇİ (WEST OF KONYA ) AREA

Abstract

The basement of the investigated area is Silurian-Cretaceous aged basement rocks. The basement rocks consists of phillite, schist, quartzite, limestone, dolomite, spilite, diorite, gabbro, diabase and serpentinite. This basement is overlined unconformably by Upper Miocene-Lower Pliocene aged Sille formation, Yalıtepe formation, Ulumuhsine formation, Küçükmuhsine formation, Lower Pliocene aged Yürükler formation and Upper Pliocene-Quaternary aged Topraklı formation. Sille formation consists of red conglomerate, sandstone and mudstone, deposited in alluvial fan and braided stream environments. Yalıtepe formation contains cream, brown stromatolitic limestone formed in a shallow lake environment. Ulumuhsine formation is made by cream, limestone, clayey limestone, clayey limestone-mudstone alternation, mudstone, marl, dolomite, nodules and bands of chert-bearing, fossils-bearing limestone deposited in a shallow and open lake environment. Küçükmuhsine formation formed in a shallow and open lake environment consists of tuffite. Yürükler formation overlies conformably and unconformably in local Ulumuhsine and Küçükmuhsine formations, and contains conglomerate, and caliche nodulled mudstone deposited in alluvial fan and braided Stream environments. All these lithologies is overlined unconformably by Upper Pliocene-Quaternary aged Topraklı formation. Topraklı formation consists of conglomerate deposited in alluvial fan and braided stream environments. Neogene basin in the region have characteristics of an intra-mountain basin, time to time controlled by tectonics.
