Geostandards 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.

Geochemistry and Fuid-Inclusion Microthermometry of the Farsesh Barite Deposit, Iran [PDF]
Geologos, 2014 Abstract The Permian carbonate-hosted Farsesh barite deposit is located southeast of the City of Aligudarz in the province of Lorestan, Iran. Structurally, this deposit lies in the Zagros metallogenic belt and the Sanandaj-Sirjan Zone.

Petrography, microthermometry, and isotopy of the gold veins from Vetas, Santander (Colombia) [PDF]
Earth Sciences Research Journal, 2020 The gold mineralization located in Vetas, Santander, consists of auriferous quartz veins hosted in Bucaramanga gneiss rocks, intrusive Jurassic rocks, and intrusive to porphyritic Miocene rocks. This study identified four mineralizing events: (1). Sericite, carbonate (ankerite and calcite?), massive and microcrystalline quartz, sphalerite, adularia ...

Nucleation-assisted microthermometry: A novel application to fluid inclusions in halite
Chemical GeologyHalite 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]
Estonian Journal of Earth Sciences, 2023 The Late Ordovician marks an epoch of substantial change during Earthâs geologic history. It documents the first mass extinction event of the Phanerozoic, which wiped out a plethora of marine genera.
