Abstract Ordovician and Silurian siliciclastic, volcanic, plutonic rocks in the southern Appalachian eastern Blue Ridge western Inner Piedmont, formerly interpreted as components of an obducted Taconic arc terrane, are recognized parts paired arc/back-arc system that formed on seaward edge Laurentian plate. New crystallization ages from metamorphosed plutonic-volcanic intruding intercalated wit...

The Tarim basin is a large composite and superimposed sedimentary that has undergone complex multi-period polycyclic tectonic movements. Understanding the proto-type tectono-paleogeographic evolution of this important for understanding basin-mountain coupling dynamical mechanisms Paleo-Asian Tethys systems as well hydrocarbon exploration development. Based on previous works, together with recen...

Opening of the Japan Sea back arc basin was accompanied by extensional tectonics in drifting southwest arc. Various trends Early Miocene grabens suggest multi-directional rifting, which necessarily involved strike-slip components some basin-margin faults. However, such are not well understood. In this work we conducted a field survey Ichishi on northern side Median Tectonic Line, central Japan....

New geochemical data including Sm/Nd isotopic data show evidence for an early Paleozoic arc/back-arc complex in the Nashoba terrane of southeastern New England. The Nashoba terrane lies between rocks of Ganderian affinity to the northwest and Avalonian affinity to the southeast. It consists of early Paleozoic mafic to felsic metavolcanic and metasedimentary rocks that were intruded by intermedi...
