TLDR
In this paper, an empirically derived relationship between the chemical composition of a carbonate in the CaCO3-(Ca, Mg)(CO3)2-FeCO3 system and the function 103 In α at 100°C is 103 ∆ α = 8.94XCaCO3 + 9.29XMgCO3+ 8.77XFeCo3 where Xi is the mole percent of component i in the carbonate.About:

Comparison of clumped isotope signatures of dolomite cements to fluid inclusion thermometry in the temperature range of 73–176 °C
TL;DR: In this article, the Δ47 results from dolomite cements for which precipitation temperatures were determined independently using fluid inclusion microthermometry were compared to previously published laboratory-derived calibrations for synthetic calcites.

Mineralogy, Fluid Inclusion, and Stable Isotope Constraints on the Genesis of the Roudný Au-Ag Deposit, Bohemian Massif
TL;DR: The Roudný gold mine in the Czech Massif Central has been studied in this paper, showing that gold is present as macro-and microscopic electrum (fineness 658-665) and invisible gold in the crystal structure of early sulfides (As-rich pyrite and Sb-rich arsenopyrite).

Dawsonite formation in the Beier Sag, Hailar Basin, NE China tuff: A natural analog for mineral carbon storage
TL;DR: In this paper, the authors determined the rock types, the authigenic minerals, the paragenetic sequence, and the origin of dawsonite in pyroclastic rocks from the Yimin Formation of Beier Sag in the Hailar Basin, China.

Dolomitic paleosols in the lagoonal tetrapod track-bearing succession of the Holy Cross Mountains (Middle Devonian, Poland)
TL;DR: The Eifelian Zachelmie succession consists of several transgressive-regressive cycles, 1 to 3m thick, starting with evenly laminated marly-shaly dolomicrites and transitioning upward into irregularly laminated dolomitic laminites with well-preserved sedimentary textures as discussed by the authors.
Journal ArticleDOI
Adsorption and mineral trapping dominate CO2 storage in coal systems
TL;DR: Gilfillan et al. as mentioned in this paper showed that CO2 has been stored in coal and sandstone formations since the Mesozoic through a combination of adsorption and mineral carbonation reactions.

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.
Journal ArticleDOI
On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.
Journal ArticleDOI
The use of bromine pentafluoride in the extraction of oxygen from oxides and silicates for isotopic analysis
TL;DR: In this paper, a technique was developed in which bromine pentafluoride was used as a reagent for quantitative liberation of oxygen from oxides and silicates, and the results of isotopic analyses were compared with measurements made in other laboratories by other procedures.
Journal ArticleDOI
Measurement of O18O16 ratios of total oxygen of carbonates
TL;DR: The commonly used phosphoric acid procedure for the determination of oxygen isotope abundances in carbonates involves a large kinetic isotope effect as mentioned in this paper, which leads to an overestimate of the dolomite-calcite oxygon isotope fractionation by 0.8 per mil.
