Ophiolitic rocks

The Stravaj ophiolite compex, part of the western Mirdita ophiolite belt in Albania, is located east of the Shpati massif, and west of the Shebenik massif. The Stravaj ophiolite sequence itself consist of MOR-related and subductionrelated volcanic rocks (Hoeck et al. 2007) formed by pillow lavas and various dykes.

High-pressure and ultrahigh-pressure metamorphic rocks crop out widely in the northern Aegean. In many instances their ages and tectonic setting are poorly constrained. Here we report newly discovered high-pressure rocks of continental crustal origin and of Late Cretaceous age southwest of the Marmara Sea. They occur at the contact between the Rhodope-Strandja Zone in the north and the Sakarya Zone in the south.

The regionally important dismembered ophiolitic sequence from the southern Kahramanmaraş region, located along the Arabian-Eurasian collision zone in southeastern Turkey, contains harzburgitic tectonites, ultramafic to mafic cumulates, isotropic gabbros and ophiolite-related metamorphic rocks. The ultramafic-mafic cumulate rocks are composed of wehrlite, lherzolite, olivine websterite, olivine gabbronorite, olivine gabbro and gabbro.

The Eocene sequence of the southern Thrace Basin unconformably overlies two types of basement: Slate, limestone and phyllite crop out in small inliers under the Upper Eocene conglomerates and limestones in the Mecidiye region, north of Saros Bay. These low-grade metamorphic rocks form the eastern extension of the Circum-Rhodope Belt of Greece.

Al-rich spinels were rarely reported compared to Cr-spinels, which were mostly observed in ophiolitic rocks. Pleonaste [(Mg, Fe2+)Al2 O4 ], which is an Al-rich spinel, was observed in the ophiolitic mafic–ultramafic rocks tectonically located in the Early Cretaceous accretionary complex, at the eastern part of the Armutlu peninsula, NW Turkey.
