Syenites are relatively rare within the Nigerian Basement Complex. As a result of their rarity, these rocks have been given less research attention over time and consequently poorly understood. The syenitic at Igarra were studied to ascertain tectonic evolution using geochemistry. Sampling was carried out survey-type geological field mapping approach. A total 10 samples collected for laboratory...

The Aegean–Hellenic arc is a deformed sector of long heterogeneous orogenic system (Tethyan belt), constituted by an inner old metamorphic crystalline core flanked younger chains European and African affinity, running from the Anatolian to Pelagonian zones. Due convergence between Arabian promontory Eurasian continental domain, that belt has undergone westward extrusion, accommodated oroclinal ...

The Raobazhai ultramafic complex is located in the north of Dabie Mountains and composed spinel peridotites accompanied by a few lenticular mafic metamorphic rocks. are mostly harzburgite, along with minor dunite lherzolite. This study reports petrological, geochemical, Re-Os isotopic data chromite harzburgites from Raobazhai. major trace whole-rock geochemistry characteristics indicate that ro...

Abstract One of the longest arcs in world originated from complexity subduction zones is Sunda Arc that covers 80% Indonesia's active volcanoes, Andaman, Sumatra, Java, and Lesser Islands. Previous research magmatism has conceded continental crust west becomes progressively oceanic towards east. However, recent suggested basement more widespread than previously thought. Therefore, this study ai...
