Silicate–natrocarbonatite liquid immiscibility in 1917 eruption combeite–wollastonite nephelinite, Oldoinyo Lengai Volcano, Tanzania: Melt inclusion study
Primary silicate–melt and carbonate–salt inclusions occur in the phenocrysts (nepheline, fluorapatite, wollastonite, clinopyroxene) in the 1917 eruption combeite–wollastonite nephelinite at OldoinyoExpand

Shulamitite Ca3TiFe3+ AlO8 - a new perovskite-related mineral from Hatrurim Basin, Israel
Shulamitite, ideally Ca 3 TiFe 3+ AlO 8 , is a mineral intermediate between perovskite CaTiO 3 and brownmillerite Ca 2 (Fe,Al) 2 O 5 . It was discovered as a major mineral in a high-temperatureExpand

Trace-element partitioning in perovskite: Implications for the geochemistry of kimberlites and other mantle-derived undersaturated rocks
Abstract Perovskite is a common groundmass phase in many mantle-derived undersaturated rocks (e.g., kimberlites), serving as an important repository for rare-earth elements (REE), high-field-strengthExpand

Can pyroxenes be liquidus minerals in the kimberlite magma
Clinopyroxene and orthopyroxene are generally rare in kimberlites, and believed to originate from disintegrated mantle and crustal xenoliths. We report occurrence of inclusions of low-Ca and high-CaExpand

Djerfisherite in the Udachnaya-East pipe kimberlites (Sakha-Yakutia, Russia): Paragenesis, composition and origin
Djerfisherite, an unusual potassium- and chlorine-bearing sulphide K6Na(Fe,Ni,Cu)(24)S26Cl, is found in remarkably fresh rocks of the Udachnaya-East kimberlite pipe, including several varieties ofExpand
