Revised stratigraphy of the Tertiary deposits of Istanbul and their engineering properties
Abstract For over 50 years, the Upper Oligocene–Upper Miocene sedimentary sequence in Istanbul has been considered to be formed of two distinct sequences separated by an unconformity. However, recent field observations and an analysis of numerous borehole data indicate the Gürpınar, Çukurçeşme and Güngören Formations are in fact a single sequence of alternating clay–sand/sandstone beds/lenses, here named the Avcılar Formation. The Bakırköy Formation, which is typically composed of carbonate rocks, conformably overlies the Avcılar Formation. The paper provides the geotechnical parameters of the units within the Avcılar Formation which it is hoped will facilitate selecting suitable geotechnical and engineering geological parameters to represent the deposits and minimize errors in the interpretation/evaluation of in-situ conditions.
