    Tectono-magmatic evolution of the younger Gardar southern rift, South Greenland by Brian G.J. Upton

    Published 2013-11-01
    “…At the unconformitybetween the Ketilidian basement and Gardar rift deposits, the YGDC expanded into a gabbroic lopolith. Its magma may represent a sample from a great, underplated mafic magma reservoir, parental to all the salic alkaline rocks in the southern rift. …”

    Magma chamber growth models in the upper crust: A review of the hydraulic and inertial constraints by Eugenio Aragón, Fernando J. D´Eramo, Lucio P. Pinotti, Manuel Demartis, José María Tubía, Roberto F. Weinberg, Jorge E. Coniglio

    Published 2019-05-01
    “…In contrast, if the roof of magmatic chambers loses the self-supporting capacity, lopoliths and calderas should be expected for more or less dense magmas, respectively, owing to the growing influence of the density contrast between the host rock and the magma. …”

    Zones of PGE–Chromite Mineralization in Relation to Crystallization of the Pados-Tundra Ultramafic Complex, Serpentinite Belt, Kola Peninsula, Russia by Andrei Y. Barkov, Andrey A. Nikiforov, Larisa P. Barkova, Vladimir N. Korolyuk, Robert F. Martin

    Published 2021-01-01
    “…The lopolithic Pados-Tundra layered complex, the largest member of the Serpentinite belt–Tulppio belt (SB–TB) megastructure in the Fennoscandian Shield, is characterized by (1) highly magnesian compositions of comagmatic dunite–harzburgite–orthopyroxenite, with primitive levels of high-field-strength elements; (2) maximum values of Mg# in olivine (Ol, 93.3) and chromian spinel (Chr, 57.0) in the Dunite block (DB), which exceed those in Ol (91.7) and Chr (42.5) in the sills at Chapesvara, and (3) the presence of major contact-style chromite–IPGE-enriched zones hosted by the DB. …”
