Permo-Carboniferous magmatism and rifting in Europe: introduction

U–Pb zircon dating of the Gruf Complex: disclosing the late Variscan granulitic lower crust of Europe stranded in the Central Alps

“…We interpret these ages as the time of emplacement of charnockite and granite magmas in the crust, consistent with worldwide magmatism at that time (Lorenz and Nicholls 1984;Veevers and Tewari 1995;Wilson et al 2004). In Europe, the Permian magmatism is coeval with mafic underplating and lower crustal granitic intrusions that may partly derive from the granulitic lower crust; this event is associated with lithospheric thinning and transtensional collapse of the Variscan collisional orogen (Downes et al 1990;Burg et al 1994;Costa and Rey 1995;Schuster and Stüwe 2008).…”

Intracontinental strike-slip faults, associated magmatism, mineral systems and mantle dynamics: examples from NW China and Altay-Sayan (Siberia)

“…Much of Eurasia, experienced large-scale extensional and transtensional tectonic regimes, associated with continental scale strike-slip faults that extend from western Europe to central Asia (see Wilson et al, 2004;Nikishin et al, 2002;Metelkin et al, 2009), with bimodal magmatism and large-scale convective hydrothermal fluids that were responsible for the development of a variety of ore systems. Furthermore, Wang et al (2009) suggested that lithospheric scale shear zones were major factors in controlling magmatism during the transition from a convergent margin to an anorogenic intraplate setting.…”
