    Simulation of primary phase relations and mineral compositions in the Partridge River intrusion, Duluth Complex, Minnesota: implications for the parent magma composition

    In order to describe the composition and crystallinity of the initial (parental) magma of the Partridge River intrusion of the Keweenawan Duluth Complex, and thereby understand the mode of emplacement and soli...

    Mineralogical and isotopic evidence for phenocryst-matrix disequilibrium in the Garner Mountain andesite

    Petrographic, trace element and isotopic evidence demonstrates that magma mixing preceded the eruption of the Garner Mountain andesite. The flow contains reversely zoned plagioclase phenocrysts and amphibole p...

    A strontium isotope and trace element profile through the Partridge River Troctolite, Duluth complex, Minnesota

    Initial 87Sr/86Sr ratios down a 2,315 foot-long core (DDH-295) through the Partridge River Troctolite are lower in the depth range 710–1,410 feet (0.70443±22) than in the underlying and overlying rocks (0.70500±1...

    Complete Late Pre-Cambrian to Early Palaeozoic Orogenic Cycle in Ghana, Togo and Dahomey

    ISOTOPIC age determinations indicate the existence of a widespread 500 × 106 yr thermal and metamorphic event, the “Pan African orogeny”, which has affected most of the African shield outside three cratonic areas
