Kilyos batısında yer alan Kretase öncesi kaya istifinin en genç bölümü günümüze kadar güvenilir bir zaman
ölçeğine uyarlanamarmştır. Bu bölüm, alttan üste, bazaltik lav, kuvars kumtaşı, dolomitleşmiş kireçtaşı ve litik kumtaşışeyl
birimlerinden oluşur. Karbonat birimi, yersel olarak, Triyas başı ve ortası dönemine ait bir mikrofauna içermektedir.
Kilyos Triyası, bölgedeki üstebindirme yapısı içinde, Alt Karboniferi altlar ve Üst Kretaseyi örter. Triyas kesiti,
litoloji ve zaman bölümleri bakımından, Kocaeli Triyası ile eşleştirilebilir.
Up to the present, the youngest part of a pre-Cretaceous rock sequence lying in the Black Sea coastal area near Kilyos has not been assigned to a reliable timescale. It apparently overlies the Carboniferous rocks and includes, in ascending order, basaltic lava, quartzose sandstone, dolomitized limestone, and lithic sandstone-shale units. An Early-Middle Triassic microfauna has been recognized first in the carbonate unit. This age assignment can be generalized for the underlying and overlying rock units since they bear different lithologic aspects from those of the Carboniferous rocks. In the study area, the recently established Kilyos Triassic sequence structurally underlies the Lower Carboniferous and overlies the Upper Cretaceous, in relation to an overthrust system.
