Shells from Neolithic shell midden sites have been routinely dated in Korea, but they have not been calibrated based on the correction values (ΔR) for the marine reservoir effect (MRE). A lack of proper calibration has left dates on shells incomparable to those on terrestrial samples, and thus unusable in building the chronological sequence of shell middens. Here, we report the two new ΔR values of a pre-bomb (pre-1950) blue mussel from the south coast. We applied the two new and the two previously reported ΔR values to the three dates on marine shells from the Bibongri shell midden in southeastern Korea. Our ΔR adjusted calibration and the comparison to dates on charcoal and bone remains clarify an ambiguity in the stratigraphy and the Early Neolithic chronology at Bibongri. Our contribution is to provide the ΔR values that can be further applied to other Neolithic shell middens along the south coast.

适用于来自韩国南部海岸的新石器时代贝壳日期的新海洋储层修正值 (ΔR)

在韩国,新石器时代贝壳遗址的贝壳经常被定年,但它们尚未根据海洋储层效应 (MRE) 的校正值 (ΔR) 进行校准。由于缺乏适当的校准,贝壳上的日期无法与陆地样本上的日期相比,因此无法用于构建贝壳的时间顺序。在这里,我们报告了来自南海岸的炸弹前(1950 年前)蓝贻贝的两个新的 ΔR 值。我们将两个新的和两个先前报告的 ΔR 值应用于韩国东南部 Bibongri 贝壳中的海洋贝壳的三个日期。我们的 ΔR 调整校准以及与木炭和骨骼遗骸日期的比较澄清了 Bibongri 地层学和新石器时代早期年代学的模糊性。
