The Merensky Reef hosts one of the largest PGE resources globally. It has been exploited for nearly 100?years, yet its origin remains unresolved. In present study, we characterised eight samples reef at four localities in western Bushveld Complex using micro-X-ray fluorescence and field emission scanning electron microscopy. Our results indicate that formed through a range diverse processes. Te...

We provide results of a comprehensive mineralogical and microstructural study relict lherzolites the main ore field fresh rocks from deep structural borehole drilled in south-eastern part Kempirsay massif. Olivine orthopyroxene contain numerous pieces evidence material redistribution at different scales caused mainly by solid-state processes, such as plastic flow mantle, syntectonic recrystalli...

The presence of PGM associated with the podiform chromitites in Jurassic–Cretaceous ophiolite Sebuku Island (South Kalimantan, Indonesia) is reported for first time. Two types chromitite have been recognized; one high-Cr composition (Cr/(Cr + Al) > 0.7) occurs deep mantle, other, high-Al < 0.6), located close to Moho transition zone. TiO2-Al2O3 relations indicate affinity IAT and MORB, ch...

Baft ophiolite mélange is a part of Naein-Baft ophiolite (southeast of Kerman province in Iran). Serpentinites from Baft ophiolite mélange contain different types of spinels such as chromite, chromespinel, ferritchromite and magnetite which can reveal different stages of evolution in host serpentinites. The compositions of Baft chromites show that they belong to podiform chromitites that may ha...

• New mineralogical and geochemical data of the Köyceğiz ophiolites are presented. PGE Re-Os chromitites indicate supra-subduction zone environment. Deep mantle subduction-related processes interplayed to form high-Cr chromitites. Textural compositional characteristics mineral inclusions in podiform flourish thoughtful information about genesis ophiolite (SW Turkey). In chromitite bodies, olivi...

Mantle-melt evolution processes in the earliest stage of subduction initiation (SI) are still ambiguous. Here, we report systematic petrogeochemical and physical records SI demonstrated by Gomsiqe massif, Mirdita ophiolite. The ultramafic body consists basal lherzolites, upper harzburgites containing lentoid dunites disseminated chromitites, displaying transition petrological (Cr# spinels range...
