抄録

The writers discuss the state of the flowage of the hot springs which flow out from the gold-quartz veins in the Tertiary formations of Japan.<BR>The hot water ascends along the vein fractures from the centers of activity. The temperature of hot water and the height of the orifices or of the stopped levels of the ascending hot water rise towards the centers of activity.<BR>We can assume that the hot springs in underground passage fulfill approximately the Bernoulli's equation. We also apply the Darcy's law to the secondary flowage due to the difference in the height of the stopped levels of the ascending hot water as described above.<BR>It is noticed that the hot springs occurring in these gold-quartz veins are muriated bitter ones in the chemical properties. In the Izu peninsula, the distribution of hot springs of this kind is limited, like that of the gold-quartz veins, to the area of the Yugashima group of the middle or lower Miocene epoch. It can not be decided whether the activity of these hot springs is genetically related to the formation of the gold-quartz veins, i. e. the late igneous activity of the Tertiary period, or they only ascend along the deeply-extended fractures in the basement complex of this district represented by the gold-quartz veins.
