The creation and prolonged existence of the zone of molten native sulfur at the bottom of thermal lake within the volcanogenic-hydrothermal system (Uzon caldera, Kamchatka)

Abstract

In this study we deal with the results of five-year routine observations of physico-chemical parameters and bulk composition of the local hydrothermal “native sulfur melt - gas-water-rock” system which was created at the bottom of the Bannoe thermal lake in the Uzon caldera after a small phreatic explosion of July 7, 1989.
