台湾中部頭社泥炭地における珪藻および黄金色藻化石を指標とした過去9000年間の洪水履歴の復元

Description

<p>Toushe Peatland is located at a mountain basin, north of Sun Moon Lake, central Taiwan. The thickness of the peat layer exceeded more than 40m, and the peat continuously deposited for 90000 years. In this paper, we analyzed diatom and Chrysophyceae assemblages at 133 samples of the top 5m sediment of the peat with 2-5 cm intervals, dated until ca 9,000 cal. years BP. We found four flooding layers, Flooding I - IV, dated ca.8200 cal yBP, ca. 5200-5600 cal. yBP, ca. 4200 cal. yBP and ca.2000 cal. yBP, respectively by diatom and Sleeping cists of Chrysophyceae assemblages.</p>
