Abstract
A comparative study of the mineral-species distribution by various systems in evaporites from the Inder deposit (Kazakhstan) and in marbles of the Luc Yen deposit in North Vietnam, as well as a comparison of these locations in the distribution of species-defining elements, has been conducted. The obtained data show that both locations are almost identical in the set of species-defining elements (O, H, Si, Ca, S, Al, Na, Mg, K, C, F, Cl, and B), but slightly differ only in the Luc Yen marble enrichment in Al, Si, C, and F. The differences in the mineral abundance between evaporites and metamorphic rocks are due to landscape environments and physicochemical conditions of their formation. A comprehensive analysis of the evaporite and marble mineralogy with the identification of species-defining elements (mineral systems) may provide an objective basis for the assumption that evaporites with minor terrigenous material rocks were involved into the formation of ruby and gem spinel deposits.
期刊介绍:
Geology of Ore Deposits is a periodical covering the topic of metallic and nonmetallic mineral deposits, their formation conditions, and spatial and temporal distribution. The journal publishes original scientific articles and reviews on a wide range of problems in theoretical and applied geology. The journal focuses on the following problems: deep geological structure and geodynamic environment of ore formation; distribution pattern of metallogenic zones and mineral deposits; geology and formation environment of large and unique metallic and nonmetallic deposits; mineralogy of metallic and nonmetallic deposits; physicochemical and isotopic characteristics and geochemical environment of ore deposition; evolution of ore-forming systems; radiogeology and radioecology, economic problems in exploring, developing, and mining of ore commodities.
