Garnet Lherzolite as the Source of Tholeiitic Melts in Kamaʻehuakanaloa
CHEMISTRY AND EVOLUTION OF EARTH’S INTERIOR AS RECORDED BY MANTLE PLUMES I POSTER
volcanology, geochemistry and petrology | 13 december 2023
Susana Hoyos, Stephanie M. Krein, Timothy L. Grove
The mantle source composition of low-silica, TiO2-rich Hawaiian tholeiitic lavas is an ongoing debate between two contrasting models: a pyroxenite sou...
