Microfacies Properties of Adilcevaz Limestone (North of Lake Van)

Abstract

in this study, the sedimentological characteristics of lower Miocene (Burdigalian) aged Adilcevaz limestone that outcrops north of lake Van were determined by means offacies analysis. Using these data, an approach to establish the Lower Miocenepaleogeography of the study area was made. After field studies, laboratory studies were undertaken and the limestone was separated into 6 micro facieses. These are 1. Wackestone-packstonefacies with redalgae and coarse bentonicforaminifera 2. Boundstonefacies with red algae and Bryozoa 3. Boundstonefacies with red algae and coral 4. Calciruditefacies with redalgae and coarse bentonicforaminifera 5. Wackestone-packstonefacies with Globigerinoidae 6. JVackestonefacies with red algae and Lepidocyclina sp. These facieses were used in an approach to the paleogeographical evolution of Adilcevaz limestone. Observations infieldstudies and findings infacies analysis indicate that the Adilcevaz limestone was deposited in a carbonate shelf which bears abundant red algae.
