EXTREME CHEMICAL HETEROGENEITY OF GRANITE-DERIVED HYDROTHERMAL FLUIDS: AN EXAMPLE FROM INCLUSIONS IN A SINGLE CRYSTAL OF MIAROLITIC QUARTZ

Kamenetsky V.S.; van Achterbergh E.; Ryan C.G.; Naumov V.B.; Mernagh T.P.; Davidson P. (2002)

Magma-derived fluids are important in geologic processes (e.g., metal sequestration and ore deposition) but are intrinsically transient. Samples of magmatic fluids represented by fluid inclusions in a single zoned quartz ...
FACTORS CONTROLLING CHEMISTRY OF MAGMATIC SPINEL: AN EMPIRICAL STUDY OF ASSOCIATED OLIVINE, CR-SPINEL AND MELT INCLUSIONS FROM PRIMITIVE ROCKS

Kamenetsky V.S.; Crawford A.J.; Meffre S. (2001)

Compositions of ∼2500 spinel–olivine pairs and 400 melt inclusion–spinel pairs have been analysed from 36 igneous suites from oceanic, arc and intraplate tectonic settings. Our data confirm that Cr-spinel mg -number is ...
FLUID BUBBLES IN MELT INCLUSIONS AND PILLOW-RIM GLASSES: HIGH-TEMPERATURE PRECURSORS TO HYDROTHERMAL FLUIDS?

Kamenetsky V.S.; Davidson P.; Crawford A.J.; Gemmell J.B.; Mernagh T.P.; Portnyagin M.V.; Shinjo R. (2002)

Hypotheses for the formation of many types of hydrothermal ore deposits often involve the direct contribution of magma-related fluids (e.g., Cu–Mo–Au porphyries) or their superimposition on barren hydrothermal cells (e.g., ...
IMMISCIBILITY BETWEEN SILICATE MAGMAS AND AQUEOUS FLUIDS: A MELT INCLUSION PURSUIT INTO THE MAGMATIC-HYDROTHERMAL TRANSITION IN THE OMSUKCHAN GRANITE (NE RUSSIA)

Kamenetsky V.S.; Davidson P.; Naumov V.B.; van Achterbergh E.; Ryan C.G. (2004)

Exsolution (unmixing) of the volatile element-rich phases from cooling and crystallising silicate magmas is critical for element transport from the Earth’s interior into the atmosphere, hydrosphere, crustal hydrothermal ...
KIMBERLITE MELTS RICH IN ALKALI CHLORIDES AND CARBONATES: A POTENT METASOMATIC AGENT IN THE MANTLE

Kamenetsky M.B.; Sobolev A.V.; Kamenetsky V.S.; Danyushevsky L.V.; Maas R.; Thomas R.; Pokhilenko N.P.; Sobolev N.V. (2004)

Kimberlite magmas, as the deepest probe into Earth's mantle (>150 km), can supply unique information about volatile components (hydrogen, carbon, chlorine, sulfur) in mantle-derived melts and fluids. All known kimberlite ...
MAGMATIC INCLUSIONS IN THE SEARCH FOR NATURAL SILICATE-SALT MELT IMMISCIBILITY: METHODOLOGY AND EXAMPLES

Kamenetsky V.S.; Kamenetsky M.B.; Davidson P.; De Vivo B.; Naumov V.B.; Menagh T.P.; Van Achterbergh E.; Ryan C.G. (2003)

Immiscible phase separation during the cooling and crystallisation of magmas is an inherently fugitive phenomenon and melt inclusions may provide the only remaining evidence of this process. We detail those features of ...
PETROLOGY AND GEOCHEMISTRY OF CRETACEOUS ULTRAMAFIC VOLCANICS FROM EASTERN KAMCHATKA

Kamenetsky V.S.; Sobolev A.V.; Joron J.L.; Semet M.P. (1995)

The origin, evolution and primary melt compositions of late Cretaceous high-K ultramafic volcanics and associated basalts of Eastern Kamchatka are discussed on the basis of a study of the mineralogy and geochemistry of the ...
THE PALAEOPROTEROZOIC KOMATIITE-PICRITE ASSOCIATION OF FINNISH LAPLAND

Hanski E.; Rastas P.; Huhma H.; Kamenetsky V.S. (2001)

The large range of chemical variation within intimately associated highly magnesian volcanic rocks in the Palaeoproterozoic Central Lapland Greenstone Belt prompted the construction of a new classification scheme for ...
