Preservation of inherited argon in plagioclase crystals and implication for residence time after reservoir remobilization

Germa, Aurélie Kimball, Selena Martens, Abigail

We compare K-Ar ages obtained on groundmass and plagioclase from lava domes that erupted after flank collapse events in the Lesser Antilles and Ecuador. All samples contain plagioclase with distinct zoning patterns, as well as inclusion-rich zones, that reveal one or more crystal resorption events due to rapid temperature changes. In these...
