Pollen analytical studies of the local Atsuma Formation, which consists of Picea and Abies conifers in the late Pleistocene, have indicated a sub-cold climate. AMS14C dating performed in a pollen analytical study of the AZK-101 core revealed 2,000 ye

We performed AMS14C-dating of twelve samples from the basin of Azuma River including HAP-1 and AKP-1 core samples, which were not 14C-measured in 2015 due to machine trouble with the Tandetron AMS system at Nagoya University. The sedimentary water co

Geological studies and AMS 14C dating of machine-drilling cores (AZK-103, AZK-112) and hand-operated drilling cores (HAP-1, AKP-1) by peat sampler from the upper Pleistocene to the Holocene, in the basin of the lower part of the Azuma River, Hokkaido

Study on vegetation development based on the results of stratigraphy, AMS14C dating and diatom analysis of Late Pleistocene to Holocene-period drill cores along Hokkaido's Azuma River

The lower part of the AZK-103 core consisted of Picea forest , and the part above it consisted of 86% Sphagnum. Above this, the proportion of Quercus forest decreased gradually. At the lowermost part of the AZK-112 core, coniferous forest material co
