Mineral Phase Paragenesis in Explosive Ejecta Discharged by Recent Eruptions in Kamchatka and on the Kuril Islands. Part 2. Accessory Minerals of the Tolbachik Type Diamonds

Abstract

The explosive atmospheric electrogenic paragenesis we studied was found to contain over 100 mineral species, varieties, and non-crystalline phases (carbonaceous minerals, phases and compounds, native metals and alloys, carbides, silicides, nitrides, halides, chalcogenides, oxides, silicates and alumosilicates, and oxysalts. The paragenesis is characterized by an abnormally low level of mineralogical organization, which indicates a deep origin of the material in the explosive facies of volcanic eruptions, including carbonaceous minerals, phases, and organic compounds.
