  • Initiation of delta formation and subsequent fluvial sedimentation in the upper delta plain

    Open Access•Kazuaki Hori, Yuji Ishii et al.•ARTICLE•The Holocene•2026•Referencias: 7

    This study investigates the Holocene evolution of the upper Kiso River delta in central Japan, focusing on sedimentary processes and accumulation patterns in the upper delta plain near the upstream limit, an area directly influenced by transgressive and regressive phases driven primarily by eustatic sea-level change and less explored than the lower delta plain. The analysis is based primarily on a 23-m sediment core (UK) retrieved from a floodbas…

  • Radiocarbon Dating of the City Wall in the Old City of Herat, Afghanistan and Hypothesis Based on the Dating

    Tetsuya Ando, Hiroyuki Kitagawa et al.•ARTICLE•Journal of Architecture and…•2024•Referencias: 3

    In this study, samples taken from the remaining parts of the city wall of the Old City of Herat were analyzed through radiocarbon dating to determine the date of construction for the first time. The results indicate that the city wall was most probably constructed between AD 441-649 (likely between AD 535-649). AD 535-649 roughly coincides with the period between the construction of the defensive wall of Gorgan and the destruction of the Sasanian…

    A surface-water Δ 14 C record of AD 1948–1999 in the tropical South China Sea (SCS) has been reconstructed from accelerator mass spectrometric radiocarbon measurements of annual bands of a Pontes coral collected from Con Dao Island, Vietnam. Results gave the following Δ 14 C time series: a steady state of −47.8 ± 2.8‰ (mean ± SD, n = 8) during 1948–1955 (i.e. in the pre-bomb period); a sharp increase during 1956–1966; a gradual increase during 19…

  • Age Determination of the Kawagodaira Volcanic Eruption in Japan by 14 C Wiggle-Matching

    Open Access•Sayaka Tani, Hiroyuki Kitagawa et al.•ARTICLE•Radiocarbon•2013•Citada por: 1•Referencias: 14

    The Kawagodaira Volcano is located on the northwest slope of Amagi Volcano on the Izu Peninsula of central Japan. The fine pumice that erupted from Kawagodaira Volcano is widely distributed in the central and western parts of the Japanese mainland. Here, we report an accurate eruption age determined by radiocarbon wiggle-matching of a Japanese cedar timber excavated from the pyroclastic deposit at the pumice flow terminal of Kawagodaira Volcano. …

  • Integration of the Old and New Lake Suigetsu (Japan) Terrestrial Radiocarbon Calibration Data Sets

    Open Access•Richard A Staff, Gordon Schlolaut et al.•ARTICLE•Radiocarbon•2013•Citada por: 5•Referencias: 18

    The varved sediment profile of Lake Suigetsu, central Japan, offers an ideal opportunity from which to derive a terrestrial record of atmospheric radiocarbon across the entire range of the 14 C dating method. Previous work by Kitagawa and van der Plicht (1998a,b, 2000) provided such a data set; however, problems with the varve-based age scale of their SG93 sediment core precluded the use of this data set for 14 C calibration purposes. Lake Suiget…

  • Evidences for centennial dry periods at ~3300 and ~2800 cal. yr BP from micro-facies analyses of the Dead Sea sediments

    Open Access•Ina Neugebauer, Achim Brauer et al.•ARTICLE•The Holocene•2015•Citada por: 3•Referencias: 18

    Laminated lake sediments from the Dead Sea basin provide high-resolution records of climatic variability in the eastern Mediterranean region, which is especially sensitive to changing climatic conditions. In this study, we aim on detailed reconstruction of climatic fluctuations and related changes in the frequency of flood and dust deposition events at ca. 3300 and especially at 2800 cal. yr BP from high-resolution sediment records of the Dead Se…

  • Radiocarbon Chronology of the DSDDP Core at the Deepest Floor of the Dead Sea

    This study establishes the chronological framework of the sedimentary sequence deposited Dead Sea, ICDP 5017-1, Radiocarbon chronology during the past 50 ka at the deepest part of the Dead Sea (the ICDP 5017-1 site), which was recovered by the Dead Sea Deep Drilling Project (DSDDP) under the auspices of the International Continental Scientific Drilling Program (ICDP). The age-depth model is constructed using 38 14 C dates of terrestrial plant rem…

  • Cave occupations in Southeastern Arabia in the second millennium BCE

    This paper reports the results of excavation at Mugharat al‐Kahf (WTN01) in Wādī Tanūf, North‐central Oman. It also provides information on the nonmortuary and nonsedentary activities in central Oman during the Wādī Sūq period (2000–1600 BCE), as the subsistence and social arrangements of this period are the subject of much debate. Previous surveys had discovered a substantial amount of Wādī Sūq pottery at the site. This project took forward the …
