Abstract

A new occurrence, as small grains associated with prehnite, chlorite and mesolite in a rodingitized hornblende gabbro of Guatemala, is reported for vuagnatite. The gabbro is part of the northern ultramafic zone of Guatemala. Physical and chemical data (microprobe analysis) are presented and are in excellent agreement with data for the Turkish vuagnatite
