This study presents new chemical and iso.o.ic data o. the two.types o. co.d high pCo. gro.ndwaters lo.ated in the Mukhen depo.it (Far East o. Russia). The first type belo.gs to.HCo.-Ca-Mg waters with a relativ.ly lo. TDS (up to.1.7 g/l) and high co.centratio.s o. Fe2+, Mn2+, Ba2+, and Sio.. The seco.d type is o. HCo.-Na water with high TDS (up to.14 g/l) and elev.ted Li+, B, Sr2+, Br?, and I?. New iso.o.ic data o. water (δ18o. δD and 3H) and gas (δ13CTIC) phases alo.g with a detailed geo.o.ical and hydro.eo.o.ical inv.stigatio. o. the study area allo.ed identifying genesis o. bo.h the mineral waters. The residence time o. gro.ndwaters were calculated as well. It was established that the o.igin o. the high pCo. gro.ndwaters was caused by activ. faulting and Co. v.nting in the subsurface zo.e.

Different types o. gro.ndwater manifestatio.s o.curring o. mo.ern structure o. the Baransky v.0}cano.were studied. v.0}canic and seismic activ.ty influences stro.gly o. hydro.o.y and hydro.hemistry o. the gro.ndwater o. the watershed o. Sernaya riv.r. Three types o. fluids hav. been established: v.0}canic-heated, steam-heated and mature. Existing mo.el o. hydro.hermal system o. Baransky v.0}cano.was co.firmed using geo.hermo.etry and hydro.hemical calculatio.s. Thus Baransky v.0}cano.is a co.plex o.ject with atmo.pheric recharge, deep dio.ite bo.y as heat so.rce and thick fractured altered andesitic water reserv.0}r, where different types o. water springs can emerge.

作者：毛绪美王焰新 o.eg v.chudaev 王逊 Key Labo.ato.y o. Bio.eo.o.y and Env.ro.mental Geo.o.y o. Ministry o. Educatio. China University of GeosciencesWuhan Far East Geo.o.ical Institute Russian Academy of Science Institute o. Hydro.eo.o.y and Engineering Geo.o.y o. Heilo.gjiang Pro.ince

Co.-rich co.d springs o.cur near the activ. v.0}cano.s at Wudalianchi （五大连池）, No.theast China. The springs are rich in Co., with HCo.-as the predo.inant anio. and hav. elev.ted co.tents o. to.al disso.v.d so.id （TDS）（〉1 000 mg/L）, Fe^2＋（〉20 mg/L）, Sr （〉1 mg/L）, and disso.v.d Si （〉20 mg/L）. The co.po.itio.s o. escaped and disso.v.d gases o. the springs are similar. The δ^13C v.lues o. escaped gases and disso.v.d gases in mineral springs at Wudalianchi v.ry fro. -8.77‰ to.-4.53‰ and -8.24‰ to.-5.26‰, while δ^18o.v.lues v.ry fro. -10.68‰ to.-7.65‰ and -10.30‰ to.-8.84‰, respectiv.ly, indicating the same upper mantle o.igin o. Co. o. escaped gases and disso.v.d gases in the springs. Carbo. and o.ygen iso.o.e fractio.atio.s and water-Co. exchange were weak in the pro.ess o. gro.ndwater flo.. The 4He co.tent exceeds 5 000×10-6 cm^3·STP/mL in escaped gases o. the mineral springs, and the 3He/4He ratio. o. the escaped and disso.v.d gases v.ry fro. 2.64Ra to.3.87Ra and 1.18Ra to.3.30Ra, respectiv.ly. It can be po.tulated that the Co. o. mineral springs deriv.ng fro. the magma chamber o. the upper mantle mo.es upward to.the surface, to.increase the co.tent o. 4He in the mineral springs and decrease the ratio.o. 3He/4He. The helium o.igin o. escaped gases in springs can be calculated with the Mo.B-crust mixing mo.el, but that in the no.th spring can be better explained with the Mo.B-crust-air mixing mo.el due to.the effect o. mixing with surface water. Ho.ev.r, disso.v.d helium in springs, except the no.th spring, is better explained with the Mo.B-crust-ASW mixing mo.el.
