ZusammenfassungDie „IUGS Subcommission on the Systematics of Igneous Rocks“ unterbreitet hier ihre Empfehlungen für die Benennung und Klassifizierung pyroklastischer sowie gemischt pyroklastisch-epiklastischer Ablagerungen auf Grund deskriptiver, hauptsächlich granulometrischer, Kriterien. Diese Empfehlungen sind das Resultat einer internationalen Umfrage mittels Fragebogen, die sich über die letzten vier Jahre erstreckte.AbstractThe IUGS Subcommission on the Systematics of Igneous Rocks herein… 

Geochemistry of Mesoproterozoic Deonar Pyroclastics from Vindhyan Supergroup of Central India: Evidences of felsic magmatism in the Son valley

Deonar Pyroclastics of Semri Group in the Vindhyan Supergroup originated as a result of violent and explosive intrabasinal submarine volcanism during the Mesoproterozoic period. These pyroclastics
