The Madra Çay Delta Archaeological Project, First Preliminary Report

“…3), and found a number of interdigitating deposits of terrestrial and marine/swamp material. This borehole was very close to the previous deep sounding by Erol in 1975 (see Section 2 above), and it was from this sounding that Erol established his basic model for marine transgressions in coastal Western Anatolia during the Holocene. The results of Erol's work have always been in dispute, however, especially since the later coastline work by Kayan at the Besik Bay near Troy and on the Datca peninsula, and the opportunity to re-examine the geomorphological sequence of the Madra £ay delta with the more advanced analytical and dating techniques now available was considered to be of crucial importance.…”

“…3). His findings suggested that the delta had been affected several times by fluctuations in relative sea-level during the Holocene, during which three separate fluvial stages were sandwiched between three marine transgressions, as depicted in his borehole stratigraphy (Erol 1975: cross-sections 1-2) ( Fig. 4).…”

“…The first geomorphological research in the delta was carried out by Erol (1975) who drilled a single bore-hole down to a depth of 38 m near the shoreline of the delta in a water well of the Ankara University property, c. 4 km. north of the mouth of the Madra Cay (Fig.…”

Ankara Kilinde Örselenme Etkisinin ve Derinliğe Bağlı Zemin Özelliklerinin Jeoteknik Arazi ve Laboratuvar Deneylerine Bağlı Olarak İncelenmesi

“…Bu özellikleri sebebiyle günümüze kadar pek çok jeoteknik ve jeolojik çalışmanın konusu olmuştur (örn. Ördemir vd., 1965;Erol, 1973;Sürgel, 1976;Birand, 1978;Kasapoğlu, 1980;Kiper, 1983;Ergüler ve Ulusay, 2003;Koçkar, 2006;Avşar vd., 2009;Çokça ve Tilgen, 2010;Met ve Akgün, 2015;Dağar, 2017;Akgün vd., 2017;Kayabaşı, 2020). Ankara Kili, çökelim ortamları ve jeolojik formasyonlar açısından Üst Pliyosen-Pleistosen flüvyal sedimanlar, taşkın ovalarındaki Kuvaterner teraslar ve yakın dönem alüvyon birimlerden oluşmuştur (Pliyo-Kuvaterner birimler).…”

“…Üst Pliyosen birimlerde ise yüksek oranda CH, CL ve MH birimleri bulunmaktadır (Şahin, 2022). Bu sedimanter birimler, bölgenin jeolojik geçmişindeki flüvyal ve iklim rejimlerine bağlı olarak farklı düzeylerde yüzey kurumasına ve erozyona maruz kalmıştır (Erol, 1973). Bu etkiler, belirli birimlerde 150 ila 180 metre derinlikteki rezidüel zeminlerin karşılığı olan bir önkonsolidasyon basıncının oluşmasına neden olmuştur.…”
