Description:
This special issue is dedicated to Yuri Taran's outstanding
contributions to gas geochemistry that began in the early
1980s with his work on deuterium and 18O compositions of
geothermal waters in the Mutnovsky (Kamchatka) region and
continues to this day with work on the Kamchatka volcanic
volatile budget, carbon isotopes of hydrocarbons, and new
insights into the geochemistry of El Chichón volcano,
Chiapas. Yuri has contributed greatly to the field of volcanic
gas geochemistry and was the first to recognize the distinct
deuterium and oxygen isotopic composition of fumarole
condensates from volcanoes in Kamchatka (Taran et al.
1987a). The shift in δD and δ18O to significantly heavier
values compared to local meteoric water led Yuri to introduce
the term “andesitic water” (Taran et al. 1989a, b) which has
since been recognized at subduction zone volcanoes globally.
This distinct isotopic composition is evidence that volcanoes
release water that ultimately originates as subducted seawater
and is recycled through the mantle wedge back to the earth's
surface. Yuri's early work on the gas emissions from
Kamchatka and Kurile Islands volcanoes also included the
development and testing of gas geothermometers (Taran
1986) and investigating hydrothermal alteration using isotopic
data (Taran et al. 1987b). His curiosity remained focused
on the isotope systematics of volcanic gases discharging from
Kamchatka and the Kuriles through the late 1980s and 1990s
with publications on the gas compositions of Klyuchevskoi
(Taran et al. 1991), Mutnovsky (Taran et al. 1992),
Avachinsky and Koryaksky (Taran et al. 1997). Yuri was
involved in the discovery of a pure and unique rhenium
mineral on Kudryavy volcano (Korzhinsky et al. 1994) and
provided one of the most detailed chemical studies of high
temperature (up to 950°C) fumaroles to date of any volcano
(Taran et al. 1995). His 1995 paper on Kudryavy remains
highly cited and provides the highest quality volcanic gas
data which also include trace elements from a subduction
zone. Such data are crucial when we attempt to interpret
lower temperature volcanic gas compositions or calculate rare
metal fluxes from volcanoes worldwide. His most recent
publication on Kamchatka-Kurile volcanic emissions provides
a detailed analysis of the total gas flux from these
volcanoes (Taran 2009).
