Fluid inclusions in migmatites

1985
The fluid inclusions provide petrologists with the only direct method for studying a possible metamorphic fluid from a high P-T environment. Basic principles of a fluid inclusion study are as old as modern petrography (Sorby, 1858), but only in recent years have advances in the technology (heating-freezing stages), and in the understanding of fluid ...

The analysis of fluid inclusions in halite

Geochimica et Cosmochimica Acta, 1988
Abstract A technique has been developed to drill into fluid inclusions in halite, to extract the inclusion fluids, and to determine the concentration of all of the major and some of the minor constituents in these fluids. The minimum diameter of usable fluid inclusions is ca . 250 μm. After dilution, the fluids are analyzed by ion chromatography and

Fluid inclusions in stony meteorites

Journal of Geophysical Research: Solid Earth, 1983
We describe fluid inclusions in five stony meteorites: diogenite ALHA 77256 and chondrites Bjurbole (H4), Faith (H5), Holbrook (L4), and Juin (H5). This brings to seven the number of stony meteorites in which fluid inclusions have been confirmed. The fluid inclusions in diogenite ALHA 77256 display a vapor bubble that decreases in volume from −180°C ...

Radiogenic isotopes in fluid inclusions

Lithos, 2001
Abstract Radiogenic isotopes studied in fluid inclusions are still a limited field, with great potential for expansion as analytical techniques improve. The main limitation for Sr, Ar and He isotope work is the very small number of radiogenic atoms produced in a typical fluid inclusion. The requirements to analysts are correspondingly high.

Fluid inclusions in mantle xenoliths

Lithos, 2001
Abstract Fluid inclusions in olivine and pyroxene in mantle-derived ultramafic xenoliths in volcanic rocks contain abundant CO2-rich fluid inclusions, as well as inclusions of silicate glass, solidified metal sulphide melt and carbonates. Such inclusions represent accidentally trapped samples of fluid- and melt phases present in the upper mantle, and

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
