| 摘要 | We have analyzed 531 stable isotope records of archaeological Mytilus shells collected from Liang island archaeological sites (LDDWI; ~8300-7400 yrBP), Matsu area, 61 stable isotope records of modern Mytilus samples, and 36 hydrogen and oxygen isotope analyses of water samples collected from Matsu area to reconstruct the Holocene paleoenvironment of Matsu area.
Mean hydrogen and oxygen isotope values of water samples are -4.2 ± 2.1‰ (N＝18; V-SMOW) and -1.0 ± 0.3‰ for Nangan; and -3.7 ± 2.3‰ (N＝18) and -1.0 ± 0.4‰ for Beigan, Matsu. Based on the isotope values and salinity observed, the water oxygen isotope values show the seasonal fluctuation and is related to the amount of freshwater mixed with the seawater.
Mean carbon isotope values of 2 modern Mytilus shells are respectively -2.2 ± 0.6‰ (N=31; boiled) and -0.0 ± 0.4‰ (N＝30; not boiled). Mean oxygen isotope values of 2 modern Mytilus shells are respectively -2.0 ± 0.7‰ and -1.9 ± 0.6‰. Mean carbon and oxygen isotope values of 11 archaeological Mytilus shells are respectively 0.5 ± 0.5‰ and -1.2 ± 0.5‰ (N=531).
There is no significant difference in mean carbon isotope values between modern not boiled and archaeological Mytilus shells. However, the mean oxygen isotope value of archaeological Mytilus shells is greater than that of modern. The ~8300-7400 yrBP water temperature was probably cooler than that of present.
Seasonal fluctuation in oxygen isotope values are observed in both modern and archaeological samples. Based on the most complete six samples, the harvest seasons were Spring-Summer (N = 3), Summer-Autumn (N = 1), and Winter (N=2). |
