Multiphase inclusions in plagioclase from anorthosites in the Stillwater Complex, Montana: implications for the origin of the anorthosites

Immiscible Fe- and Si-rich silicate melts in plagioclase from the Baima mafic intrusion (SW China): Implications for the origin of bi-modal igneous suites in large igneous provinces

“…Immiscible Fe-and Si-rich melts have been reported to be important during the differentiation of the Skaergaard intrusion in East Greenland (Jakobsen et al, 2005;Veksler, 2006), Sept Iles intrusion in Canada (Charlier et al, 2011), Stillwater Complex in the USA (Loferski and Arculus, 1993) and Panzhihua intrusion in SW China . Melt inclusions that have mineral assemblage and shapes resemble those from the Baima intrusion have been reported in Skaergaard intrusion (Hanghøj et al, 1995;Jakobsen et al, 2011).…”

The Stillwater Complex, Montana – Overview and the significance of volatiles

“…chloride solution, their stratigraphic location suggests they could have been liquids filter-pressed out from the underlying anorthosite. Loferski and Arculus (1993) have described multiphase inclusions consisting of clinopyroxene + ilmenite + apatite that occur within plagioclase from the Middle Banded series of the intrusion. The textures and constant modal mineralogy of the inclusions indicate that they were incorporated in the plagioclase as liquid droplets that later crystallized rather than as solid aggregates.…”

Silicate Liquid Immiscibility within the Crystal Mush: Late-stage Magmatic Microstructures in the Skaergaard Intrusion, East Greenland

“…This low-volume residual liquid would react with adjacent primocrysts to form olivine, Fe^Ti oxides, Ca-rich clinopyroxene and Ca-and Al-rich plagioclase (e.g. Loferski & Arculus, 1993;Veksler et al, 2007). The liquid in the upper reaches of the mush is probably hotter (by perhaps a few degrees) and the width of the liquid miscibility gap is smaller, compared with that at the base of the mush (although see Boorman et al, 2004).…”
