The protoliths of central himalayan eclogites
WebbThe protoliths of these metabasites were the Permian Panjal Trap basalts (ca. 267 ± 2.4 Ma), which were emplaced along the northern margin of Indiawhen it was part of Gondwana. After the break-up of Gondwana, India drifted northward, subducted beneath Asia and underwent UHP metamorphism during the Eocene (ca. 45±1.2Ma).

Andesitic rocks of island arc or continental margin are renowned for their Ni (and Cr) depletion, but this is not the case for Weihai eclogites.

Webb4 mars 2024 · The tectonic location, Neoproterozoic Ocean island basalt (OIB)-like mafic volcanic rocks and eclogite protolith of the EOKB imply the presence of the Neoproterozoic mantle plume magmatism as well as its contribution for enrichments of Ni-Cu-Co beneath EKOB. The ultramafic complexes show a close spatio-temporal relationship with eclogites.
