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:

Reconnaissance isotope chemostratigraphy of Neoproterozoic carbonate rocks in western Tasmania
TL;DR: A reconnaissance carbon and strontium isotope study of several Neoproterozoic-Cambrian units in western Tasmania has been carried out by as mentioned in this paper, which provides new information on the age and correlation of the units.

Facies control on selective dolomitization and its impact on reservoir heterogeneities in the Samana Suk Formation (middle Jurassic), Southern Hazara Basin (NW Himalaya, Pakistan): an outcrop analogue
Mumtaz M. Shah,Hamad ur Rahim,Hamad ur Rahim,Aosaf Hassan,Muhammad Raza Ul Mustafa,Imran Ahmad +5 more
TL;DR: In this article, an attempt has been made to understand degree of diagenetic alterations (i.e., dolomitization) within various limestone facies due to fluid-rock interaction phenomenon, and its impact on the reservoir behavior of altered rocks based on field investigations, petrographic studies, stable isotope signatures and porosity/permeability analysis.

Mineral, fluid and thermal evolution in veins from late orogenic coal basins of the Cantabrian Zone (Variscan, NW Spain)
TL;DR: In this paper, a detailed study of syn-tectonic mineral veins and textural features of fluid inclusions is presented for reconstructing the fluid and thermal evolution in diagenetic and very low-grade metamorphism environments.

Lithological nature of the subduction channel: Insights from the Karabakh suture zone (Lesser Caucasus) and general comparisons
TL;DR: In this paper, the lithological nature of major interplate boundaries is estimated by a field analysis of a well preserved exhumed subduction channel in the Caucasus Karabakh region, which is comprised of an upper "sedimentary" channel formed by an upper section of detrital and volcanic rocks thrusted on top of pelagic sediments scrapped off the oceanic floor.

Clumped isotope acid fractionation factors for dolomite and calcite revisited: Should we care?
TL;DR: In this article, the authors show that calcite has an acid fractionation factor independent of the reaction method, while all four dolomites show significant differences between the two methods with the sealed vessel reactions showing much smaller acid fractionations than the common acid bath.

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.

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.

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.
