SEDIMENTOLOGICAL PROPERTIES and DEPOSITIONAL ENVIRONMENTS of the HOLOCENE SEQUENCE in YENİKAPI, ISTANBUL
Başlık: SEDIMENTOLOGICAL PROPERTIES and DEPOSITIONAL ENVIRONMENTS of the HOLOCENE SEQUENCE in YENİKAPI, ISTANBUL
Yazarlar: Meltem SEZERER BULUT, M.Namık YALÇIN, Oya ALGAN
Anahtar Kelimeler: Holocene, sedimentology, grain size distribution, Theodosian Harbor, İstanbul
Özet:

During the salvage excavations in the area of the former Theodosian harbor in Yenikapı-Istanbul several ship wrecks from the Byzantine period, archaeological objects from different periods and a Holocene sedimentary sequence have been uncovered. In this study the lithological, lithostratigraphical and facies properties of the Holocene sequence were investigated in detail and its depositional environment was determined. For this purpose, 14 different sections of a total thickness of 17.75 m along four archeological profiles (S1, S2, S3, S4) were studied and 100 samples collected. The grain size distribution of samples was defined by sieve and sedigraph analyses and the mineralogical composition by XRD method. Results of these analyses and facies characteristics of this poorly known Holocene sequence were used for the definition of the depositional environment. Accordingly, the marine sediments are deposited in near-shore environment, with a natural embayment or estuary transgressively. Terrigenous and anthropogenic materials carried by the Lycos River at the mouth of this natural embayment resulted first in a regression and then a high-energy fluvial system in the study area.

Abstract:

During the salvage excavations in the area of the former Theodosian harbor in Yenikapı-Istanbul several ship wrecks from the Byzantine period, archaeological objects from different periods and a Holocene sedimentary sequence have been uncovered. In this study the lithological, lithostratigraphical and facies properties of the Holocene sequence were investigated in detail and its depositional environment was determined. For this purpose, 14 different sections of a total thickness of 17.75 m along four archeological profiles (S1, S2, S3, S4) were studied and 100 samples collected. The grain size distribution of samples was defined by sieve and sedigraph analyses and the mineralogical composition by XRD method. Results of these analyses and facies characteristics of this poorly known Holocene sequence were used for the definition of the depositional environment. Accordingly, the marine sediments are deposited in near-shore environment, with a natural embayment or estuary transgressively. Terrigenous and anthropogenic materials carried by the Lycos River at the mouth of this natural embayment resulted first in a regression and then a high-energy fluvial system in the study area.
