Ophiolites are the remnants of ancient oceanic crust and upper mantle that were tectonically emplaced into continental margins. They display the only evidence for magmatic, tectonic, and hydrothermal processes associated with seafl oor spreading prior to 170 Ma because no oceanic lithosphere older than this age is preserved in the modern oceans. The occurrence of sheeted dikes, side-byside tabu...

Ophiolites of the Alpine belt derive from closure Mesozoic Tethys Ocean that was interposed between palaeo-Europe and palaeo-Adria continental plates. The orogeny has intensely reworked oceanic rocks into metaophiolites with various metamorphic imprints. In Western Alps, continental-derived units are distributed within two paired bands: An inner band where subduction-related high-pressure (HP) ...

Determining absolute ages of orogenic faults is critical to understanding the deformation process in upper crust, but obtaining age remains a problem due lack readily available techniques. Carbonates occur as veins range geological settings, and thus it suitable mineral for U-Pb geochronology. Here, we apply new approach dating on syn-tectonic dolomite from Gelouang gold deposit western Qinling...

The metallogenic belts (or regions) of the Sanjiang orogenic domain are divided under ideas systematic, hierarchical and correlated geological-tectonic unit, based on spatial–temporal structure MABT evolution → intracontinental convergence strike-slip tectonic transformation process.
