秋田駒ヶ岳白滝の石灰華 Calcareous sinters from Shirataki Fall at Mt. Akita-Komagatake
Calcitic calcareous sinters are deposited along a dried dale near Shirataki Fall at Mt. Akita-Komagatake. The sinters contain such impression fossils as <i>Fagus crenata Blume, Sasa kurilensis Makino et Shibata</i>, and <i>Prunus nipponica Matsum</i>. They would have precipitated from low-temperature carbonated spring water gushing out at the border of the atrio, at the time of explosive activity on the southern foot of Mt. Medake in 1932.
