Metamorphic Fluids: The Evidence from Fluid Inclusions

1986
Detailed microscopic studies of rocks from virtually all terrestrial environments show that one or more minerals in these rocks contain small quantities of liquid (or glass) and/or vapor trapped in cavities generally less than 50 microns in diameter. These are fluid inclusions, and they provide us with samples of the fluid phase present in the rock at ...

Inclusion of Antioxidants in Resuscitation Fluids

1988
Hemorrhagic shock is, whenever possible, treated with rapid volume replacement. Such treatment is often initiated by paramedical personnel as soon as possible following blood loss, e.g., at the site of an accident and during transport to an emergency room.

Fluid Inclusions and Isotopic Signatures

2016
Low salinity aqueous fluid inclusion and arsenopyrite geothermobarometry support mineralogical estimates of mineralisation P-T conditions between 300° and 400 °C and 10–14 km depth. Isotopic data show that the mineralising fluids had extensive interaction with host rocks and/or were derived from the host rocks. Aditional input of some meteoric water is

Fluid inclusions: tectonic indicators

Journal of Structural Geology, 1999
Abstract During the first half of the 20th century fluid inclusions have been studied in ore geology in order to determine the chemistry and physical parameters (density) of the mineralising fluids. Apart from a few pioneering works in the middle of the century, fluid inclusions were not used as structural markers before the late 1980s.

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
