Is quartz a potential indicator of ultrahigh-pressure metamorphism? : laser Raman spectroscopy of quartz inclusions in ultrahigh-pressure garnets
Laser Raman microspectroscopy was applied to quartz inclusions in coesite- and diamond-grade metapelites from the Kokchetav ultrahigh-pressure metamorphic (UHPM) complex, Northern Kazakhstan, and diamond-grade eclogite xenoliths from the Mir kimberlite pipe, Yakutiya, Russia to assess the quantitati...
