KUDRIAVY volcano on Iturup island in the Kuril arc is an active calc-alkaline volcano. It has not erupted this century; its current volcanic activity is characterized by hot (up to 910oC) gas jets which have been stable for at least 30 years. The composition of the gaseous emissions is typical of high-temperature fumaroles, but we report here the discovery of unusual subsurface sublimates associated with one gas jet—a sulphide mineral containing rhenium as the only cation. To our knowledge… 
Geochemistry of magmatic gases from Kudryavy volcano, Iturup, Kuril Islands
Volcanic vapors were collected during 1990–1993 from the summit crater of Kudryavy, a basaltic andesite volcano on Iturup island in the Kuril arc. The highest temperature (700–940°C) fumarolic
Rhenium enrichment in the northwest Pacific arc
Abstract Rhenium (Re) is one of the least abundant elements in the silicate Earth. However, independent rhenium sulfide was reported in the Usu and Kudryavy volcanos, namely rheniite (ReS2, 74.5 wt%
Sources of unique rhenium enrichment in fumaroles and sulphides at Kudryavy volcano
Rhenium (Re) is one of the least abundant elements in Earth, averaging 0.28 ppb in the primitive mantle. The unique occurrence of rheniite ReS2 (74.5 wt% of Re) in Kudryavy volcano precipitates
Fumarolic incrustations at Kudryavy volcano (Kamchatka) as a guideline for high-temperature (>850 °C) extinct hydrothermal systems
Abstract Our knowledge of active magmatic hydrothermal system (or magmatic vapors) is largely related to the modeling of geochemical processes including heterogeneous equilibrium calculations with
FLUXES AND SOURCES OF VOLATILES DISCHARGED FROM KUDRYAVY, A SUBDUCTION ZONE VOLCANO, KURILE ISLANDS
Abstract The Kudryavy volcano, a 996-m-high basaltic-andesite cone on the northeastern shore of Iturup Island in the Kuriles, erupted last in 1883 and has since been in a persistent state of
HIGH TEMPERATURE VOLCANIC GAS GEOCHEMISTRY (MAJOR AND MINOR ELEMENTS) AT KUDRYAVY VOLCANO, ITURUP ISLAND, KURIL ARC, RUSSIA
Kudryavy volcano is well known for its famous Re-enrichment (Korzhinsky et al., 1994). Degassing occurs along 2 main fumarolic fields: field A enriched in Re (T= 400 to 700°C) and field B enriched in
Sources of rhenium and osmium enrichment in fumaroles, sulphide sublimates and volcanic rocks from the Kudriavy volcano
Rhenium loss through magma degassing could be partly balanced by rhenium enrichment in fumarolic magmatic gases and Re-bearing precipitates, as may be the case for the Kudriavy volcano associated
Behavior of highly-siderophile elements during magma degassing: A case study at the Kudryavy volcano
Abstract The capacity of natural vapor phase to transport metallic elements is not unambiguously established relative to that of a liquid hydrothermal phase. We measured highly-siderophile element
Volatile transport of metals in the andesitic magmatic-hydrothermal system of White Island
Volcanic gases observed at active volcanoes originate from the magma at depth. These volatiles exsolve as a result of decompression, crystallization and cooling of the silicate melt. The transport of
Enhanced mantle-to-crust rhenium transfer in undegassed arc magmas
TLDR
Observations of high rhenium concentrations and low Yb/Re ratios in arc-type melt inclusions indicate strong enrichment of Rhenium in undegassed arc rocks, and consequently the continental crust, which results in a crustal estimate of ∼2 p.p.b.rhenium, as compared to previous estimates.
