Scientific paper

By means of general crystallization models it is shown that in general the observed partition coefficients for trace element distribution between phenocrysts and host lava are not equilibrium coefficients. This disequilibrium between the host lava and the phenocrysts, as far as trace element partitioning is concerned is due to an imbalance between the rate of crystal growth and trace element diffusion in the lava and in the crystal. It is suggested that the inverse correlation of grain size and certain trace-element concentrations for lunar basalts and oceanic tholeiites might be due to these kinetic effects.
