Bulk distribution coefficient

Cebria and Lopez-Ruiz (1995) proposed a method to calculate mantle source concentrations, bulk distribution coefficients (D) and constant... [Pg.128]

For a multi-mineral system, the bulk distribution coefficient, D, is the combination of the for each mineral weighted by the fraction of each mineral in the system, and is defined as follows ... [Pg.1701]

A common application of this equation to trace element modeling is to examine the variations in trace element abundances and ratios for elements with different bulk distribution coefficients (Figure 7). In this plot, F is the fraction of melt for equilibrium crystallization, F proceeds from... [Pg.1702]

Figure 7 Illustration of the effects of equilibrium (batch) crystallization or melting on trace element abundances, (a) Variation in liquid concentration (Cl) (normalized to unit source concentration Cq= 1) as a function of melt fraction (F) for six elements with different bulk distribution coefficients (D). (b) Change in the ratios of incompatible elements with different Ds as a function of F. Each curve is for a different pair of elements that have the Z)s indicated. Note that when D < 0.1, incompatible element ratios can be changed only at very low extents of melting (or high extents of crystallization) (Langmuir et al., 1992) (reproduced by permission of American Geophysical...

The distribution coefficient for the chromatographic retention process is similar to the bulk distribution coefficient studied in supercritical fluid extraction. Reaction rates in supercritical fluid solvents as a function of pressure are determined by the change in partial molar volume (Avj) between the products and reactants. [Pg.161]
