Proterozoic-early Paleozoic ophiolites of the Andean Basement of southern South America
(Geological Society of America, 2000-11)
We describe a series of Middle Proterozoic to early Paleozoic ultramafic and mafic rocks in the basement of the Central Andes that have different geochemical attributes and paleogeographic settings. Several ophiolitic belts ...
Ophiolite Emplacement and the Effects of the Subduction of the Active Chile Ridge System: Heterogeneous Paleostress Regimes Recorded in the Taitao Ophiolite (Southern Chile)
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2009)
Caracterização química de cromitas nos maciços de cromínia e mairipotaba, goiás, Brasil
(2010-03-01)
Metaultramafic bodies tectonically emplaced within the metasedimentary sequence of the Araxá Group are associated with an ophiolitic melange in southeast Goiás. In the region of Crominia - Mairipotaba, they occur as ...

A melt-focusing zone in the lithospheric mantle preserved in the Santa Elena Ophiolite, Costa Rica
(2015-08-01)
The Santa Elena Ophiolite in Costa Rica is composed of a well-preserved fragment of the lithospheric mantle that formed along a paleo-spreading center. Within its exposed architecture, this ophiolite records a deep section ...

The enigma of crustal zircons in upper-mantle rocks: Clues from the Tumut ophiolite, southeast Australia
(2015)
We suggest a new explanation for the presence of crustally derived zircons in the upper-mantle rocks of ophiolitic complexes, as an alternative to subduction-related models. Integrated isotopic (U-Pb, Hf, and O isotopes) ...
