Abstract
In boreholes from Pauzhetka Springs (South Kamchatka) are prehnite associated paragenetically with laumontite and apparently albite; its association with quartz is unstable in the presence of laumontite or within the temperature range examined. Prehnite occurs only at depths exceeding 290 m and is formed at 150 to 190°C., as a product of hydrothermal alteration of volcanogenic rocks, under certain conditions. Epidote is invariably elastic in every borehole and its origin is unrelated to hydrothermal alterations except perhaps in a few isolated cases suggestive of its micro-recrystallization in cavities. — V.
