The ophiolite-related Mersin Melange, southern Turkey: its role in the tectonic–sedimentary setting of Tethys in the Eastern Mediterranean region [PDF]
WOS: 000222988100001The Mersin Melange underlies the intact Mersin Ophiolite and its metamorphic sole to the south of the Mesozoic Tauride Carbonate Platform in southern Turkey The Melange varies from chaotic melange to broken formation, in which some ...

Ultrahigh Pressure Metamorphism: Cambridge Topics in Petrology
The field of ultra‐high pressure metamorphism (UHPM) emerged only 12 years ago when microscopic relics of coesite were found in crustal rocks that had been metamorphosed during subduction related to continental collision. Coesite‐bearing metamorphic rocks were soon found elsewhere, and then metamorphic microdiamonds were discovered.

ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages

Introduction Khoy ophiolite at the global scale is in the middle part of the Alp-Himalaya orogenic belt and it is extended over 3900 Km2 which indicates remnant Neotethys oceanic lithosphere in the Mesozoic era (Kananian et al., 2010). In this paper, in

ABSTRACT Laser ablation U–Pb single zircon geochronology was applied to four peraluminous granite and granodiorite samples from the Bassiès pluton in the Central Pyrenees (France) yielding a wide range of concordant ages from early Carboniferous (Tournaisian, 351 Ma) to early Permian (Artinskian, 285 Ma).

ABSTRACT We analyse variations in Brune stress drop (Δσ), apparent stress (τa) and Savage–Wood radiation efficiency (ηsw = τa/Δσ) during the 2010–2014 Pollino seismic swarm (Southern Apennines, Italy). This prolonged sequence included multiple swarms, with a Mw 5.2 event in October 2012, preceded by a Mw 4.3 event in May 2012, followed by aseismic slip.

Post-Hercynian ultrahigh-temperature tectono-metamorphic evolution of the Middle Atlas lower crust (central Morocco) revealed by metapelitic granulite xenoliths [PDF]
The study of metapelitic sillimanite- and garnet-bearing granulite xenoliths brought to the surface by the basanite of the 650 ka Tafraoute maar shed new light on the lower crust of the Tabular Middle Atlas (Morocco).

Was the Formation of the North Anatolian Fault Influenced by the Aegean Extension?
ABSTRACT The North Anatolian Fault (NAF), one of the most prominent plate boundary continental fault systems on Earth, facilitates the westward movement of the Anatolian microplate into the Aegean region. The temporal and spatial evolution of the NAF is important for understanding the mechanism of escape tectonics during plate interaction in active ...
