Dating results showed that sedimentation started at 100.4 ± 6.6 ka BP over the Upper Miocene formations and ended at 39.1± 2.5 ka BP.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this paper, fluvial deposits overlying Upper Miocene formations, located in 5 km northeast of Çanakkale city, was investigated using Optically Stimulated Luminescence (OSL) method and deposition age of the sequence was determined from quartz sands collected from three levels of the reference site.
📊
Key Findings & Data:Based on petrographic composition and stratigraphic characteristics, alluvial materials might have accumulated as the combination of hyperconcentrated flow deposits, cohesive debris flow deposits and floodplain deposits.
💡
Conclusion & Impact:Dating results showed that sedimentation started at 100.4 ± 6.6 ka BP over the Upper Miocene formations and ended at 39.1± 2.5 ka BP.

Abstract

In this paper, fluvial deposits overlying Upper Miocene formations, located in 5 km northeast of Çanakkale city, was investigated using Optically Stimulated Luminescence (OSL) method and deposition age of the sequence was determined from quartz sands collected from three levels of the reference site. Based on petrographic composition and stratigraphic characteristics, alluvial materials might have accumulated as the combination of hyperconcentrated flow deposits, cohesive debris flow deposits and floodplain deposits. Accordingly, it seems disputable to assume these accumulations as former terrace deposits of the Sar ı çay Stream. Dating results showed that sedimentation started at 100.4 ± 6.6 ka BP over the Upper Miocene formations and ended at 39.1± 2.5 ka BP. Keywords: Optically Stimulated Luminescence, Fluvial deposits, Dating, Strait of Çanakkale, Çanakkale

Özet

Bu çal ı ş mada, Çanakkale’nin 5 km kuzeydo ğ usunda Üst Miyosen formasyonlar ı n ı uyumsuz olarak örten akarsu çökelleri I ş ı k Uyar ı ml ı Lüminisans (OSL) yöntemi ile incelenmi ş ve seçilen referans istifin 3 farkl ı seviyesinden al ı nan kuvars kumu örneklerinden çökel birikim ya ş ı belirlenmi ş tir. İ stifin petrografik bile ş imi ve stratigrafik özelliklerine göre çökelme a ş ı r ı doygun akma, moloz akmas ı ve ta ş k ı n düzlü ğ ünde as ı l ı malzemenin durulmas ı ş eklinde gerçekle ş mi ş olmal ı d ı r. Buna göre istifin genel bir ifade ile Sar ı çay’ ı n eski taraça dolgular ı olarak tan ı mlanmas ı ş üphelidir. Tarihlendirme verilerine göre Miyosen formasyonlar ı üzerine sedimantasyon günümüzden 100.4 ± 6.6 bin y ı l önce ba ş lam ı ş ve 39.1± 2.5 bin y ı l önce sona ermi ş tir.
