A Neoproterozoic age for the chromitite and gabbro of the Tapo ultramafic Massif, Eastern Cordillera, Central Peru and its tectonic implications [PDF]
, 2011 The ultramafic-mafic rocks of the Tapo Complex are exposed in the Eastern Cordillera of the Central Peruvian Andes. This complex is composed of serpentinised peridotites and metabasites with some podiform chromitite lenses and chromite disseminations and

Abiotic Methane Generation via CO2 Hydrogenation With Natural Chromitite Under Hydrothermal Conditions [PDF]
Geochemistry, Geophysics, Geosystems, 2021 In modern continental serpentinization systems and ultramafic rock‐hosted sub‐seafloor hydrothermal systems, it is believed that chromitite plays an important role in abiotic hydrocarbon generation.

The Cedrolina Chromitite, Goiás State, Brazil: A Metamorphic Puzzle [PDF]
Minerals, 2016 The Cedrolina chromitite body (Goiás-Brazil) is concordantly emplaced within talc-chlorite schists that correspond to the poly-metamorphic product of ultramafic rocks inserted in the Pilar de Goiás Greenstone Belt (Central Brazil). The chromite ore displays a nodular structure consisting of rounded and ellipsoidal orbs (up to 1.5 cm in size), often ...

Metamorphism on Chromite Ores from the Dobromirtsi Ultramafic Massif, Rhodope Mountains (SE Bulgaria) [PDF]
Geologica Acta, 2009 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.
