Mg-rich staurolite and kyanite inclusions in metabasic garnet amphibolite from the Swedish Eastern Segment: evidence for a Mesoproterozoic subduction event

Mesoproterozoic continental growth: U–Pb–Hf–O zircon record in the Idefjorden Terrane, Sveconorwegian Orogen

“…The Sveconorwegian metamorphism is significantly older in the Idefjorden Terrane (1.05-1.02 Ga; Johansson et al, 1993;Bingen et al, 2008b;Söderlund et al, 2008;Austin-Hegardt, 2010) than in the Eastern Segment (0.99-0.96 Ga; Johansson, 1998;Christoffel et al, 1999;Söderlund et al, 2002;Möller et al, 2007). The high-pressure signature of the metamorphism in the Eastern Segment allows for a model of continental subduction-exhumation of the Eastern Segment relative to the Idefjorden Terrane (Möller, 1998(Möller, , 1999Austin-Hegardt et al, 2005;Austin-Hegardt, 2010;Mohammad et al, 2011). (3) The structural style in the Idefjorden Terrane and Eastern Segment are different.…”

Zircon U-Pb Emplacement and Nd-Hf Crustal Residence Ages of the Straussburg Granite and Friersdale Charnockite in the Namaqua-Natal Province, South Africa

“…Major elements were analysed on fused rock powders using an Hitachi S-3400N scanning electron microscope with Oxford instruments energy-dispersive X-ray spectrometer (SEM-EDS) as described by Mohammad et al (2011). Precision and accuracy were assessed using international rock powder standards, e.g.…”
