AMS14C dating performed in a pollen analytical study of the AZK-101 core revealed 2,000 years of vegetation history. The history started from Picea, Abies, and Thuga in the Younger Dryas period approximately 12,000 years ago in Zone A, followed by Betula in Zone B, Juglans in Zone C, and Quercus (Lepidobaranus) with Picea in Zone D. Variations in vegetation occurred on the barren land appearing after the marine regression 5,700 years ago in the core areas. Specifically, an increase in Quercus (Lepidobaranus), an increase in Alnus, an increase from Sparganium to ferns, and rapid increases followed by declines in the transition from Poaceae plants to ferns appeared in the AKP-1, ATS-1, HAP-1, and S60K core areas, respectively. Fagus genus formed small communities in these areas at the beginning of the Holocene. Analysis of the ATP-2 core revealed an increase in Sphagnum genus repeating about every 2,000 years and the spread of the Picea genus beginning at least 1,000 years ago. The tendency for Picea to increase at the very top of the cores was also shown in the AKP-1 core.", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name":
