Abstract The Middle Jurassic intracontinental shortening event in East Asia, known as episode A of the Yanshanian Movement eastern North China Craton and first phase Daebo Orogeny Korean Peninsula, respectively, has been thoroughly studied during past two decades. However, timing its beginning, duration, deformational processes are still highly controversial because few studies have probed corr...

Juxtaposition of different-grade metamorphic slices is a typical feature Phanerozoic orogens but relatively scarce in Precambrian orogens. Here, we focus on the Chengde Complex at northern segment late Paleoproterozoic Trans-North China Orogen, North Craton as case, to explore how orogeny-related metamorphism was juxtaposed The Orogen collisional orogen and records abundant information about or...

The variety of temporal and structural constraints on the Alpine tectonometamorphic signature metamorphic core Betic-Rif orogen (Alboran Domain) has supported a long-lasting debate regarding tectonic geodynamic evolution Western Mediterranean region. Uncertainty still exists timing significance (a) orogenic construction; (b) exhumation deep roots orogen; (c) transition from shortening to crusta...

-The kinematics of the Eocene episode of compression between the Iberian and European plates is examined. It is p r o p d that the boundary between the two plates extended West of the Pyrenees, dong the Spanish marginal trench to end West of King's trough at a triple point junction. The pole of relative rotation computed within this hypothesis lies near5g0N; 62"W and the resulting shortening al...

Geochemical data from the 625 Ma Massabesic Gneiss Complex of southern New Hampshire show strong affinities for other Avalonian rocks of southern New England and suggest continental rifting in the Late Proterozoic. Migmatized paragneiss, the dominant rock type in the complex, has major and trace element compositions that are compatible with graywackes from continental arcs. The paragneiss also ...

Abstract Zircon separates from the contact aureole of syn-tectonic Dawros–Currywongaun–Doughruagh Complex, western Ireland, are studied to constrain nature and timing magmatism associated with early stages Grampian Orogeny. The samples analysed come uppermost part Dalradian Supergroup in northern Connemara (the Ben Levy Grit Formation), where a laterally extensive (>10 km) package metamorpho...

Abstract The Longshou Shan of western China is the northern backstop Cenozoic Himalayan-Tibetan orogen and occupies a key linkage between Tarim continent North craton which separate pre-Cenozoic Tethyan orogenic system Central Asian system. Therefore, Paleoproterozoic–Paleozoic evolution this region critical to understanding extent overprinting deformation, construction Eurasian continent, rela...
