Cumulate granites: A perspective from new apatite MgO partition coefficients

A New Atom-Additive Method for Calculating Partition Coefficients

A new method is presented for the calculation of partition coefficients of solutes in octanol/water. Our algorithm, XLOGP, is based on the summation of atomic contributions and includes correction factors for some intramolecular interactions. Using this method, we calculate the log P of 1831 organic compounds and analyze the derived parameters by multivariate regression to generate the final mo...

A mineral and cumulate perspective to magma diferentiation

SIEVED PARTITION FUNCTIONS AND a-BINOMIAL COEFFICIENTS

The ^-binomial coefficient is a polynomial in q . Given an integer t and a residue class r modulo ;, a sieved ^-binomial coefficient is the sum of those terms whose exponents are congruent to r modulo /. In this paper explicit polynomial identities in q are given for sieved ij-binomial coefficients. As a limiting case, generating functions for the sieved partition function are found as multidim...

Apatite Application to Investigate Magmatic Evolution of Zouzan Granites, NE Lut Block

Apatite minerals of I-type Zouzan granitoids and typical garnet-bearing S-type granites have been analyzed by electron microprobe to define trace element concentrations and compare them in different granites. Zouzan granites are composed of apatites with lower Fe, Mn, Na and HREE and higher REE and ∑REE relative to S-type ones. Trace elements abundances of apatite often vary with some parameter...

Liquid/air partition coefficients of four terpenes.

The liquid/air partition coefficients of four common terpenes, alpha-pinene, beta-pinene, 3-carene, and limonene, have been determined in vitro using head space technique. The liquids used were water, human blood, and olive oil. alpha-Pinene, beta-pinene, and 3-carene were practically insoluble in water and limonene was slightly soluble; all were readily dissolved in olive oil. The oil/air part...
