Restoring Halite Fluid Inclusions as an Accurate Palaeothermometer: Brillouin Thermometry Versus Microthermometry

open access: yesGeostandards and Geoanalytical Research, 2020
Halite traps inclusions of the mother fluid when precipitating. When unchanged, the density of these fluid inclusions (FIs) records the water temperature Tf at the time of crystal formation. As halite is ubiquitous on Earth and geological time, its FIs possess a high potential as temperature archives.

Nucleation-assisted microthermometry: A novel application to fluid inclusions in halite

open access: yesChemical Geology
Halite deposits have long been utilized for interrogating past climate conditions. Microthermometry on halite fluid inclusions has been used to determine ancient water temperatures. One notable obstacle in performing microthermometric measurements, however, is the lack of a vapor bubble in the single-phase liquid inclusions at room temperature. (Pseudo-

Drivers of the Late Ordovician Mass Extinction: redox, volcanism, atmospheric oxygen/carbon dioxide and/or glaciation [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
The Late Ordovician marks an epoch of substantial change during Earth’s geologic history. It documents the first mass extinction event of the Phanerozoic, which wiped out a plethora of marine genera.

Fluid inclusions in rocks of the Archean high-grade Varpaisjärvi-Lapinlahti area, central Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1992
Fluid inclusions both in matrix quartz of metamorphic rocks and in quartz veins from five samples from the Archean high-grade Varpaisjärvi-Lapinlahti area were examined with microthermometric methods. Two types of fluid inclusions were observed: CO2-rich

Aquamarine from Massangana batholith, Rondônia State: mineral chemistry and fluid inclusion data

open access: yesREM: International Engineering Journal, 2020
Beryl is usually found in granite-pegmatite systems. The addition of chromophore elements (V, Cr, Mn, Fe) into the crystalline structure favors color changes in beryl and thus generates some of the world’s expensive gems such as emerald, morganite ...
