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:

An example for black shale development on a carbonate platform (late Triassic, Seefeld, Austria)
TL;DR: In this paper, three facies have been distinguished within a separate basin within the Hauptdolomit carbonate platform, and a μm-scaled rhythm can be observed, which was obviously seasonally controlled.

Effect of temperature on the oxygen isotope composition of carbon dioxide (δCO218O) prepared from carbonate minerals by reaction with polyphosphoric acid: An example of the rhombohedral CaCO3–MgCO3 group minerals
TL;DR: In this article, the authors measured the ratio of 18O to 16O in CO2 ( δ CO 2 18 O ) produced from rhombohedral carbonate minerals in the compositional range CaCO3-MgCO3 by reaction with polyphosphoric acid (PPA), at temperatures of between 25 and 110°C.

In vacuo reduction of silver orthophosphate with graphite for high-precision oxygen isotope analysis.
Andrzej Pelc,Stanisław Hałas +1 more
TL;DR: The reduction of silver phosphate with graphite under vacuum conditions was studied at final reaction temperatures varying from 430 to 915°C to determine theCO(2) extraction yield and the oxygen isotopic composition of CO(2).
Journal ArticleDOI
Stable 18O and 13C isotope records of Viviparus diluvianus (Kunth, 1865) shells from Holsteinian (MIS 11) lakes of eastern Poland as palaeoenvironmental and palaeoclimatic proxies
TL;DR: In this article, the oxygen and carbon stable isotope composition of V.diluvianus shells was determined in the palaeolakes of the Holsteinian interglacial (MIS 11) in eastern Poland.
Journal ArticleDOI
Palaeoenvironmental approach to the geology, mineralogy and geochemistry of an Early Miocene alluvial-fan to cyclic shallow-lacustrine depositional system in the Aktoprak Basin (central Anatolia), Turkey
Ali Gürel,Selahattin Kadir +1 more
TL;DR: In this paper, the authors used mineralogical, geochemical and isotopic characterization of cyclic sedimentation within Neogene sedimentary units in the Aktoprak Basin, Turkey, to provide important clues regarding regional palaeoclimatic changes.

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.
