TLDR
In a series of 19 runs, the partition coefficient for barium into calcite, k Ba 2+ calcite, was determined to be 0.06 ± 0.01 at 25°C and 1 bar.About:

Assessing the reliability of magnesium in foraminiferal calcite as a proxy for water mass temperatures
TL;DR: In this paper, the Mg concentrations within single chambers of the planktic foraminifer Globigerinoides sacculifer (BRADY) maintained under controlled laboratory conditions were measured at variable temperatures (19.5-29.5 °C) and constant salinity and (2) at variable salinity (22-45

Solid solution partitioning of Sr2+, Ba2+, and Cd2+ to calcite
TL;DR: In this article, a range of precipitation rates was used to study the nonequilibrium and equilibrium partitioning behaviors of minor metal ions to calcite (CaCO3(s)) in natural waters.

Sorption of divalent metals on calcite
TL;DR: In this paper, the authors measured the sorption of seven divalent metals (Ba, Sr, Cd, Mn, Zn, Co, and Ni) on calcite over a large initial metal (Me) concentration range (10−8 to 10−4 mol/L) in constant ionic strength (I = 0.1), equilibrium CaCO3(s)-CaCO3 (aq) suspensions that varied in pH.

Partition coefficients in calcite: Examination of factors influencing the validity of experimental results and their application to natural systems
TL;DR: In this article, the complexities associated with the coprecipitation of metals in calcite using the behavior of Sr and Mg, which have received the most detailed study, are examined.

The geochemistry of carbonate diagenesis: The past, present and future
TL;DR: For example, in this article, the authors present a method for interpreting carbonate diagenesis of carbonate rocks by analyzing the δ18O value of any fluid inclusions or by measuring the temperature using a method such as the clumped isotope technique.

Chemical Diagenesis of a Multicomponent Carbonate System--1: Trace Elements
Uwe Brand,Ján Veizer +1 more
TL;DR: In this article, the authors show that the degree with which a particular carbonate component approaches either the open system or the partly closed system equilibrium is determined by its respective mineralogical stability and the water/rock ratio.

The incorporation of Mg2+ and Sr2+ into calcite overgrowths: influences of growth rate and solution composition
Alfonso Mucci,John W. Morse +1 more
TL;DR: The concentrations of Mg2+ and Sr2+ incorporated within calcite overgrowths precipitated from seawater and related solutions, determined at 25°C, were independent of the precipitation rate over approximately an order of magnitude as mentioned in this paper.

Sr, Cd, Mn and Co distribution coefficients in calcite as a function of calcite precipitation rate
TL;DR: In this paper, a pH-stat was used to maintain a constant degree of saturation, and hence precipitation rate, during each coprecipitation run, and the precipitation rate was proportional to the degree of supersaturation and the mass of seed crystal introduced.

Trace element partition coefficients—a review of theory and applications to geology
TL;DR: In this article, the thermodynamics of trace element partition among coexisting phases is reviewed and the effect of temperature, pressure and phase composition on the numerical value of D is discussed.

Ionic radii for use in geochemistry
E.J.W. Whittaker,R. Muntus +1 more
TL;DR: In this paper, the ionic radii proposed by Shannon and Prewitt as the effective values in oxides and fluorides have been analysed for their conformity with the radius ratio principles of crystal chemistry.
