Алюмофторидная и алюмофосфатная минерализация жарчихинского молибденового месторождения (Западное Забайкалье)

Abstract

the article is devoted to description of mineral parageneses at the Zharkhikha molybdenum deposit. A special feature of the deposit is a presence of fluoro-beryllium, aluminumfluoride and alumino-phosphate associations as well as molybdenite. These parageneses are not typical for molybdenum deposits and assume the absence of a genetic connection between them. The aluminofluoride paregenesis includes prozopite, ralstonite, reductuite, zarcinite, scales and F-bearing mineral (up to 6.23 wt %) of the plumgumimite group with an intermediate composition of goyazite-gorceixite-florencite. In addition, there are nakrit and kaolinite. Fluor-beryllium mineralization is spatially separated from molybdenite mineralization and is represented by phenacite and bertrandite with fluorite, quartz and feldspar.
