Dualistic distribution coefficients of elements in the system mineral-hydrothermal solution. I. Gold accumulation in pyrite
Autor: T. S. Krasnoshchekova, O. Yu. Belozerova, E. E. Lustenberg, Vladimir L. Tauson, D. N. Babkin, T. M. Pastushkova
Publikováno v: Geochemistry International. 49:568-577
The use of trace elements (TE) as geochemical indicators is complicated by the dualism of their distribution coefficients D due to the additional (i.e., above the concentrations of an isomorphic component) incorporation of elements at structural defe

The effect of the crystal size in sample on the trace-element concentration
Autor: E. E. Lustenberg, Vladimir L. Tauson, T. M. Pastushkova, T. S. Krasnoshchekova, D. N. Babkin
Publikováno v: Russian Geology and Geophysics. 51:764-773
The dependence of trace-element concentration on the size of crystal in sample is experimentally studied by the example of gold distribution among single crystals of different sizes of hydrothermally grown pyrite, As-pyrite, and magnetite. The effect
