Petrology and Tectonic Setting of Dyke Swarms Emplaced in the Upper Jurassic Qorveh Granitoid Complre Mg-hornblende and annite, in composition, respectively. The mafic rocks have tholeiitic-calc-alkaline affinity. Spider diagrams imply enrichment in LILE (such as Cs, Rb, U and Pb), depletion in HFSE (Nb and Ba) and high LILE/HFSE ratio. The enrichment in LILE and Pb suggest the crustal contaminat

Intraplate Proterozoic Magmatism in the Amazonian Craton Reviewed: Geochronology, Crustal Tectonicsochemical character and geological settings, in order to arrive at an integrated tectonic interpretation. The information together with the characteristics of coeval volcanic-plutonic suites indicates a cyclicity of the mafic-felsic activity through time and space. At least four LIP/SLIP events are

Thin sections exhibit well-preserved igneous textures, with primary minerals (e.g., hornblende, clinopyroxene, plagioclase) extensively al

Spatial and Temporal Distribution Patterns of Mafic Dyke Swarms in Central Asia: Results from Remotcks and successive magma intrusions originating at depth. Dyke swarms indicate regional crustal deformation related to continental formation and evolution, and play the role of messenger regarding magma activities from the deeper crust or even mantle. The large number of mafic dykes in Central Asia

Petrology and Mineral Chemistry of a Porphyritic Mafic Dyke, Jonnagiri Schist Belt, Eastern Dharwart belt, eastern Dharwar craton, India. The undeformed porphyritic dyke is characterised by the presence of euhedral plagioclase megacrysts (0.5–3.5?cm) exhibiting primary magmatic alignment. At places, partial resorption is noticed in the plagioclase phenocrysts indicating crystal-melt interaction.
