Olivine xenocryst diffusion reveals rapid monogenetic basaltic magma ascent following complex storage at Pupuke Maar, Auckland Volcanic Field, New Zealand
Monogenetic basalts are spatially and temporally unpredictable and are commonly
interpreted to rise extremely rapidly and directly from their mantle source, increasing their …

Melt transport and mantle assimilation at Atlantis Massif (IODP Site U1309): Constraints from geochemical modeling
Abstract Olivine-rich troctolites (> 70% olivine) reveal that extensive melt impregnation of pre-
existing olivine-rich lithologies participate to the building of slow spread oceanic crust. To …

Combined Fe-Mg chemical and isotopic zoning in olivine constraining magma mixing-to-eruption timescales for the continental arc volcano Irazú (Costa Rica) and Cr …
Arc magmas commonly are mixtures of newly arriving primitive melts, stored magmas at
shallow levels, and xenolithic material added on ascent. Almost every eruption has a unique …
