..., Västerbotten, Satakunta, Ulvö and Jämtland complexes (Gorbatschev, Solyom & Johansson, 1979 ; Gorbatschev et al . 1987 ; Fig. 1 ). Three of these, the Dalarna, Jämtland and Västerbotten complexes, are apparently truncated by the Caledonian nappe front ( Fig. 1 ), suggesting that they continue westwards...

... phonolite crystallized at 650–825 °C, 100 MPa, in water-undersaturated and reducing conditions (low H 2 O content: 1.2 wt%, ΔNNO-0.5 to ΔNNO-1; Giehl et al. 2014 ). So far, neither the stability of nosean nor the crystallization of sodalite-group minerals in complex fluid (e.g., with CO 2 , S, and Cl) has...

... of different affinities, and reflect continental growth. However, despite their tectonic significance and the complexity of the processes that form them, they are poorly understood. Serpentinites, which are highly lubricating and easily weathered, are key elements in understanding subduction and exhumation...

... alteration reactions took place. All of these features provide important new information that refines our understanding of a genetic model for VHMS mineralization and so provides additional advantages to mineral exploration for such deposits. The Mesoproterozoic (Keweenawan) Duluth Igneous Complex...

... amphibole are scant, yet hold the potential to yield comparable information. To that end, calcic amphibole from late-stage rocks of the English Peak plutonic complex (EPC; Klamath Mountains, northern California) was analyzed in situ, in textural context. The pluton's late stage consists of three nested...

... investigations commonly have complex internal structures due to growth and modification during magmatic and metamorphic events. For instance, this is well known to occur in zircons, whose internal structure may be characterised by “age domains”, each of which refers to a single geological event. Baddeleyite...

... ulvöspinel, (Fe 2+ ↓) A (Fe 2+ ↑) B TiO 4 , the magnetic structure is perfectly antiferromagnetic, so that the expected net magnetization is zero. Determining the net magnetization of oxidized titanomagnetites (titanomaghemites) is more complex, as the magnetic moment depends on the site ordering...
