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.

Characterization of H2S bearing fluid inclusions
Bulletin de Minéralogie, 1984Rarely 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.

Raman microspectrometry of fluid inclusions
Lithos, 2001Abstract 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 ...

Chinese Journal of Geochemistry, 1992
Presented in this paper are the types, salinities, homogenization temperatures and organic components of fluid inclusions formed at the four stages of diagenetic authigenesis in the Eogene of the Biyang Depression. The results of cooling experiments on fluid inclusions were used to determine the fluid system and composition of saline aqueous solution ...

Chemical Geology, 1987
Abstract In graphite-buffered COH 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, 1991Abstract 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
1985Fluid 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
