Abstract

The genetic conditions of calcareous sinters were studied with special reference to their crystalline form. The samples investigated were collected from Kunimi Hot Springs, Iwate Pref., and some other springs in Japan. In addition to the solution temperature and the magnesium concentration in solution, the supersaturation with calcium carbonate may be of assistance in the prediction of crystalline forms. A high degree of supersaturation favors the formation of aragonite, independently of the solution temperature. This is well exemplified by the sinters from Kunimi Hot Springs, where pure aragonitic deposits are forming at a temperature of 31.5℃ from hot spring water with a high activity product and a high Mg/Ca ratio.
