- •
Egyptian ophiolites were formed in forearc, MOR and MOR-arc transition setting.
- •
The Mozambique oceanic lithosphere underwent partial melting of about 15–35%.
- •
The melt was extracted under oxidizing conditions.
- •
The peridotites were interacted with arc melts causing cryptic metasomatism.
- •
Neoproterozoic mantle of Egypt is might be similar to those of the younger age.
