Middle-Upper
Miocene terrigenous and marine sedimentary rock units deposited in Truva basin
outcrop throughout the eastern shore of Dardanelles. These deposits overlie
unconformably Paleozoic schists, marbles, quartzites, Permian-Triassic
ophiolites and Eocene volcanic rocks between Çanakkale and Truva; only Eocene
volcanics and volcanoclastic deposits in the vicinity of Lapseki, north of
Çanakkale. The sedimentary rock units are composed of Middle Miocene Sarıyar
formation and Upper Miocene Çanakkale formation. Sarıyar formation overlying
metamorphic and magmatic basement units with an angular unconformity contains
red-dark red colored alluvial deposits. Çanakkale formation containing marine
deposits overlies Sarıyar formation with an unconformity. Çanakkale formation
consists of Güzelyalı, Tekkedere and İntepe members that have distinctive
lithological components, sedimentary features and depositional environments.
These are transitive laterally and vertically to each other. Güzelyalı member
that contains mainly fine to coarse sandstones, and lesser amounts of
mudstones, siltstones and conqlomerates deposited on beach and shoreface.
İntepe member is composed of mudstones and siltstones deposited and sandstones.
Sandstones developed with the tidal processes have Maden Teknik ve Arama Genel
Müdürlüğü, Jeoloji Etütleri Dairesi, Ankara. bidirectional
cross-stratifications, planar and trough cross-stratification, flaser and
lenticular beds. Tidal channel deposits that have erosional bases in lagoon
mudstones are observed. These are made of medium to coarse sandstones,
conglomerates and abundant broken shell fragments. Tekkedere member contains
algal mat limestones, oolitic limestones being a product of shoals, and
conglomerates and coarse sandstones beach. Upper Miocene Çanakkale formation is
overlain by Pleistocene marine terraces and Pleistocene-Recent alluvial
dreposits.
