Microparagenesis of diamonds and native aluminum in ejecta of recent volcanism

The particles of native aluminum that were extracted from ejecta of the 1988 Klyuchevskoi eruption were found to contain numerous inclusions of ultramicrodiamonds of the cuboctahedral habitus. We discuss the results of X-ray spectroscopy, X-ray structural, and spectroscopic studies of minerals that...

Description
Summary:The particles of native aluminum that were extracted from ejecta of the 1988 Klyuchevskoi eruption were found to contain numerous inclusions of ultramicrodiamonds of the cuboctahedral habitus. We discuss the results of X-ray spectroscopy, X-ray structural, and spectroscopic studies of minerals that support the previous inference as to electric-shock–stimulated crystallization of diamonds from volcanic gases.
