Large igneous provinces (LIPs) form in both oceanic and continental settings by the emplacement and eruption of voluminous magmas ranging from basalt to rhyolite in composition. Continental flood basalt provinces are the best studied LIPs and consist of crustal intrusive systems, extensive flood lavas and ignimbrites, and mafic volcaniclastic deposits in varying proportions. Intrusive rocks are...

The Lewisian Gneiss Complex (LGC) is a tonalite-trondhjemite-granodiorite (TTG)-dominated fragment of the North Atlantic Craton (NAC) in northwest Scotland. End-member models describe LGC as representing either continuous piece Archean crust or up to 12 geologically distinct terranes, with interpretations sitting on spectrum between these end-members. There particular uncertainty over correlati...

in taleghan, olivine basalt-basaltic andesite dykes as part of tertiary mamgmatic activities in central and western alborz zone, intruded into both karaj formation and late eocene-oligocene volcanic rocks. these dykes have similar geochemical characteristic which suggest that they are originated from a common source. on the primitive mantle normalized spider diagram, the dykes are characterized...

Baltica and Laurentia form the core of hypothesized Mesoproterozoic supercontinent Nuna in most paleogeographical reconstructions. Long gaps still exist paleomagnetic record Baltica, different relative configurations for have been presented. This study presents new data obtained mafic dykes on Bornholm (Denmark, southwest Baltica). We provide a 1.326 ± 0.010 Ga Group I key pole (Plat: 06°N, Plo...
