Capricorn Assemblage : ウィキペディア英語版 | Capricorn Assemblage The Capricorn Assemblage, also known as the Capricorn Formation, is a geological formation comprising the central portion of the Mount Meager massif in southwestern British Columbia, Canada. It is named after Capricorn Mountain, the third highest subsidiary peak of Meager. The assemblage was formed during a period of volcanic activity about or less than 90,000 years ago. Weathered rhyodacite is main volcanic rock of the Capricorn Assemblage. It forms the final of Capricorn Mountain and Mount Job. The rhyodacite is characterized by phenocrysts of plagioclase, quartz and biotite. Capricorn Assemblage rhyodacite underlies Plinth Assemblage rhyodacite on the south flank of Plinth Peak.〔 ==See also==
