Experimental Study of Phenakite Solubility in Aluminosilicate Melts: Implication for the Genesis of Be Deposits
The solubility of phenakite (Be2SiO4) in granite melts was experimentally studied at temperatures of 1000 and 1100°C and pressures of 1 and 4 kbar in dry conditions and in the presence of 10 wt % H2O. The starting materials were granite glasses with agpaitic coefficient of 1–2.5 and natural phenakite. It was found that the solubility of phenakite increases with increasing agpaitic index (Na + K)/Al of the melt, and the solubility of BeO in hydrous melts is higher than in dry ones. The solubility of phenakite also increases with pressure. The obtained experimental data were generalized with the previous data in the form of an equation describing the solubility of BeO in alkaline-granite melts coexisting with crystalline Be phases depending on the agpaitic index, temperature, and pressure. The results of the experiments and their generalizations support the model of Be concentration in alkaline hydrous melts—the products of differentiation of granite magmas.
期刊介绍：
Petrology is a journal of magmatic, metamorphic, and experimental petrology, mineralogy, and geochemistry. The journal offers comprehensive information on all multidisciplinary aspects of theoretical, experimental, and applied petrology. By giving special consideration to studies on the petrography of different regions of the former Soviet Union, Petrology provides readers with a unique opportunity to refine their understanding of the geology of the vast territory of the Eurasian continent. The journal welcomes manuscripts from all countries in the English or Russian language.
