Abstract Despite being a prominent continental-scale feature, the late Mesoproterozoic North American Midcontinent Rift did not result in break-up of Laurentia, and subsequently underwent structural inversion. The timing inversion is critical for constraining far-field effects orogenesis processes associated with rift's failure. Keweenaw fault northern Michigan (USA) major thrust structure rift...

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...

 Late Neoproterozoic (548-579 million years ago) metamorphic - igneous Shotor Kuh complex is cropped out in SE Shahrood, consist of a various range of rocks including metabasite, metapelite, metagraywake, metapsammite and metacarbonate. Metapelites include phyllite to gnessis and migmatite. Metamorphism intensity in the highest degree, progressed to anatexy and formation of granitic melts. Ther...

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...
