Melt/mantle interaction and melt evolution in the Sartohay high-Al chromite deposits of the Dalabute ophiolite (NW China)

, 2001
The Sartohay block of the Dalabute ophiolite consists chiefly of mantle harzburgite and lherzolite with minor dunite. These rocks host voluminous chromite deposits with lenticular or vein-like shapes.

Geochemical variations within podiform chromitite deposits in the Shetland ophiolite: implications for petrogenesis and PGE concentration

, 2015
The Shetland ophiolite, located to the NE of the Scottish mainland contains podiform chromitites. Two of these are known to host extremely anomalous PGE concentrations.

Uvarovite in podiform chromitite; the Moa-Baracoa ophiolitic massif, Cuba [PDF]

, 2018
The chromitite pods of the Moa-Baracoa massif, in the eastern ophiolitic belt of Cuba, contain pre-existing gabbro sills. This association is affected by two processes of hydrothermal alteration.

Petrogenesis of the podiform chromitites in the Luobusa ophiolite, southern Tibet.

, 1995
Podiform chromitites of the Luobusa ophiolite in the Indus-Yarlung Zangbo Suture of southern Tibet are typical of the high-Cr variety. This ophiolite is composed of a mantle sequence, a transition zone and a melange zone, and is tectonically bounded by ...

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria)

, 2021
Podiform chromitite bodies occur in highly serpentinized peridotites at Dobromirtsi Ultramafic Massif (Rhodope Mountains, southeastern Bulgaria). The ultramafic body is believed to represent a fragment of Palaeozoic ophiolite mantle.

Petrogenesis of Ophiolite-type Chromite Deposits in China and Some New Perspectives

, 2014
Ophiolites of varying ages are widespread in China, some of which contain chromite deposites of industrial value. However, compared with some of the world’s large ophiolite chromite deposites (e.g., Kempirsai, Bulquiza, Guleman), the Chinese chromite ...
