2018: A shallow origin for diamonds in ophiolitic chromitites

A shallow origin for diamonds in ophiolitic chromitites Abstract Recent findings of diamonds in ophiolitic peridotites and chromitites challenge our traditional notion of Earth mantle dynamics. Models attempting to explain these findings involve incorporation of diamonds into chromite near the mantle transition zone. However, the occurrence of metastable diamonds in this context has not been…

2018: A reappraisal of the metamorphic history of the Tehuitzingo chromitite, Puebla state, Mexico

A reappraisal of the metamorphic history of the Tehuitzingo chromitite, Puebla state, Mexico Abstract The Tehuitzingo ultramafic body (Acatlán Complex, southern Mexico) is a strongly serpentinized harburgitic body that encloses chromitite bodies and blocks of eclogitic rocks. Hydrous retrograde metamorphism on chromitite bodies resulted in the formation of: i) partly altered chromite char- acterized by…
