ABSTRACT:
Different types of groundwater
manifestations occurring on modern structure of the Baransky volcano were
studied. Volcanic and seismic activity influences strongly on hydrology and
hydrochemistry of the groundwater of the watershed of Sernaya river. Three
types of fluids have been established: volcanic-heated, steam-heated and
mature. Existing model of hydrothermal system of Baransky volcano was confirmed
using geothermometry and hydrochemical calculations. Thus Baransky volcano is a
complex object with atmospheric recharge, deep diorite body as heat source and
thick fractured altered andesitic water reservoir, where different types of
water springs can emerge.
