Infiltration of Intercumulus Liquid as a Process for the Sulfide Relocation—An Example from Low-Sulfide Mineralization of the Burakovo–Aganozero Intrusion

Autor: G. S. Nikolaev

Publikováno v: Geochemistry International. 59:491-500

A mechanism is suggested to explain the transport of sulfide material by means of its dissolution and subsequent redeposition under the effect of an ascending infiltrating flow of intercumulus melt during the compaction of cumulates in layered pluton

Publikováno v: Geochemistry International. 59:156-170

Oxygen isotope composition was studied in 33 monomineralic fractions of olivine from plagioclase lherzolite, dunite, troctolite, and olivine gabbronorite of the Yoko-Dovyren layered massif. The δ18O values of the least altered rocks not contaminated

Morphology, Mineralogy, and Composition of Sulfide Droplets in Picrodolerite from a Near-Bottom Apophysis of the Yoko-Dovyren Layered Intrusion

Autor: I. V. Pshenitsyn, S. N. Sobolev, G. S. Nikolaev, Alexey A. Ariskin, Vasiliy O. Yapaskurt, E. V. Kislov, Dmitry Korost

Publikováno v: Petrology. 28:246-262

The paper presents data on sulfide globules in picrodolerites from a bottom apophysis of the Yoko-Dovyren massif, northern Transbaikalia. Textural features of the rocks indicate that they crystallized at rapid magma cooling. Their composition is simi

SPINMELT-2.0: Simulation of Spinel–Melt Equilibrium in Basaltic Systems under Pressures up to 15 Kbar: III. The Effects of Major Components in the Melt on the Chrome-Spinel Stability and a Possible Solution of the Problem of Origin of Chromitites

Autor: G. S. Barmina, Alexey A. Ariskin, G. S. Nikolaev

Publikováno v: Geochemistry International. 58:1-10

The effect of variations in the fo, fa, en, fs, di, an and ab components in high-Mg basaltic melts on the topology of the spinel liquidus was quantified by conducting simulations with the new SPINMELT-2.0 model for the spinel–melt equilibrium. It h

Using a new model of the spinel-melt equilibrium SPINMELT-2.0, the effect of variations of fo-, fa-, en-, fs-, di-, an- and ab-components in high-Mg basaltic melts on the topology of the spinel liquidus was quantified. It has been established that en
