Description
The morphology of microscopic charcoal particles included in the soil samples obtained in Aso region, Kyushu Japan, were investigated, and the age of one soil sample was measured to know the origin and the history of the grassland there. Microscopic charcoal particles were extracted from the soil samples by the method which applied to pollen analysis correspondingly. 50 charcoal particles more than 100 microns long from each sample were observed using industrial microscope. Photographs were taken with a digital camera. On the other hand, the age of one soil sample was measured by the Tandetron AMS of Nagoya University Center for Chronological Research. Consequently, since the origins of most microscopic charcoal particles contained in each sample were considered to be the herbal plants and the forms could be classified simply, it seemed that comparatively simple herbal vegetation had continued for long period. On the other hand, since the age in the soil sample of the lowermost part of black soil where charcoal particles began to increase was 8640±35 BP, the grassland there seemed to be almost 10000 years old.
