Thermal water of the Yugawara Hot Spring

Journal Article:

Abstract

The Yugawara Hot Spring is located in the bottom of the dissected creata of the Yugawara volcano. Natural hot spring water ran dry almost twenty five years ago, and thermal water is now pumped up by means of deep drill holes. The hydrorogy of the thermal water was studied from both geochemical and geophysical points of view. Two types of thermal water, sodium chloride and calcium sulfate, are recognized. Sodium chloride is predominant in the high temperature area and low in the surrounding low temperature area. Calcium sulfate predominates in the low temperature area. Sodium chloride is probably derived from deep magmatic emanations as indicated in the high Li content. Sulfate ion seems to originate from oxidation of pyrite whose impregnation took place in the ancient activity of the Yugawara volcano. The content of Ca is stoichiometrically comparable with SO/sub 4//sup 2 -/. It is suggested that sulfuric acid derived from the oxidation of pyrite attacks calcite formed during the hydrothermal alteration of rocks. Some consideration of well logging in the geothermal area is also discussed. Temperature measurement in recharging of cold water is applicable to the logging of drill holes as well as the electric logging.
