Synmetamorphic Fluid Inclusions in Granulites

1990
Many granulites contain high density CO2-rich fluid inclusions; These have played a decisive role in the elaboration of the concept of carbonic metamorphism. It requires that some CO2-rich fluids are present during peak metamorphism, an idea now severely challenged by several workers. For synmeta-morphic inclusions, neither high density nor coincidence

Characterization of H2S bearing fluid inclusions

Bulletin de Minéralogie, 1984
Rarely described until recently, fluid inclusions with H2S as a major component have been studied in various samples of quartz, fluorite and calcite. The phase behaviour at low temperatures of H2S-bearing inclusions (sometimes containing solid S or C) and previously analyzed with the Raman microprobe, is presented.

Clues from Fluid Inclusions

Science, 2001
The reconstruction of past conditions on Earth involves a multitude of disciplines and techniques. In his Perspective, Goldstein highlights the potential of fluid inclusions in small halite or calcite crystals, formed, for example, when marine waters evaporate.

Raman microspectrometry of fluid inclusions

Lithos, 2001
Abstract For many kinds of fluid inclusions, the coupling of microthermometry and Raman microspectrometry is still the only viable option to obtain compositions of single fluid inclusions. A review is given on the basis of 16 years of experience and helped with about 120 references of the instrumentation, analytical conditions and methodology of the ...

Thermodynamic calculations of the COH system applied to fluid inclusions: Are fluid inclusions unbiassed samples of ancient fluids?

Chemical Geology, 1987
Abstract In graphite-buffered COH systems P , T and CO 2 CH 4 ratio fix the partial pressures of all the gas species. The relation between CO 2 CH 4 ratio and H 2 O content of the fluid was calculated for temperatures of 300°, 400°, 500°, 600°, 700° and 800°C and pressures of 500, 1000, 2000, 5000 and 9000 bar ...

Salinity of oceanic hydrothermal fluids: a fluid inclusion study

Earth and Planetary Science Letters, 1991
Abstract An extensive microthermometric study of quartz, epidote, plagioclase, anhydrite and sphalerite-hosted fluid inclusions from ophiolitic [Semail (Oman) and Trinity (California) ophiolites] and oceanic (East Pacific Rise hydrothermal vents, Gorringe Bank, ODP Leg 111 Hole 504B) crust has been carried out in order to constrain a model accounting

Fluid Regime in Southern Norway: The Record of Fluid Inclusions

1985
Fluid inclusions have been studied in representative rocks from Southern Norway, notably in the Bamble granulites. On the basis of the earliest fluid inclusions trapped in rock-forming minerals (mainly quartz), five major types of fluid distribution have been recognized: 2-phase aqueous (H20 dominant, without solid), carbonic (mostly pure CO2, possiDle
