Ophiolites and ophiolitic melanges of Turkey: A review
, 2013 The aim of the presented study is to review the ophiolites and ophiolitic mélanges of Turkey and their importance for constraints on the evolution of the region. On the basis of the existing data, the ophiolitic associations of Turkey are classified into three main groups. 1.

Petrogenesis and tectonomagmatic evolution of the Sabzevar ophiolitic complex based on whole rock geochemistry, zircon U–Pb geochronology, and zircon trace element composition in pillow lavas and sheeted dikes of the Sultanabad area [PDF]
پترولوژیIntroduction Ophiolitic complexes—fragments of oceanic lithosphere tectonically emplaced onto continental margins—serve as crucial archives for reconstructing the formation and evolution of ancient ocean basins.

Chrome spinel compositions as evidence for an Archaean ophiolite in the Kuhmo greenstone belt in Finland [PDF]
Bulletin of the Geological Society of Finland, 1994 Investigations into chromite compositions in Archaean ultramafic rocks are rare. Most Archaean ultramafic rocks have undergone a multi-stage history of deformation and metamorphism, and therefore fresh primary chromite is rarely preserved.

Geological Journal, EarlyView.Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...
