An exsolution origin for Archean mantle garnet
(2017)It is well established that the cratonic subcontinental lithospheric mantle (C-SCLM) represents a residue of extensively melted peridotite. The widespread occurrence of garnet in C-SCLM remains a paradox because experiments ... -
Metasomatism of the Kaapvaal Craton during Cretaceous intraplate magmatism revealed by combined zircon U-Pb isotope and trace element analysis
(2021)The origins of the mica-amphibole(K-richterite)-rutile-ilmenite-diopside (MARID) and the, presumably related, phlogopite-K-richterite-peridotite (PKP) mantle xenolith suites remain enigmatic. For instance, it is unclear ... -
Rare earth elements in olivine:determination, occurrence and behaviour
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2018)Olivine is a widely occurring mineral that offers great potential for improving our understanding of geological processes. Olivine is present across a range of geologically significant settings, occurring in stony-iron ...
