Çalışma
alanı stratigrafisi Kretase yaşlı bazalt ve bazaltik andezitler ile başlayıp bu
kayaçların ayrışması ile oluşan ürünler ile devam eder. Bu istif üzerinde İstanbul’un
güneyindeki kayaçların ayrışma ürünü kumlar yer alır ve güncel çökeller ile
sonlanır. Birimlerin fizikomekanik, kayaç değişim değeri (KDD), kayaç değişim
oranı (KDO), pelitler ile psammitlerin içerisindeki killerin serbest şişme (SŞ)
değeri hesaplanmıştır. Çalışma alanı için KDD – KDO ve KDO – KDD, porozite –
serbest şişme, porozite – birim hacim ağırlık değerleri, KDD – dane birim hacim
ağırlık, KDO – dane birim hacim ağırlık, nokta yük – KDD, nokta yük – KDO arasında güvenilir
eşitlikler önerilmiştir. Volkaniklerin orta ayrışmadan ileri ayrışma aşamasına
geçişte bölgenin volkanizma etkisinde kaldığı belirlenmiştir.
