Journal ArticleDOI
Al- and Cr-rich chromitites from the Mayari-Baracoa ophiolitic belt (eastern Cuba); consequence of interaction between volatile-rich melts and peridotites in suprasubduction mantle
TL;DR: The Mayari-Baracoa belt is a part of the east-west-trending Cuban ophiolitic belt as discussed by the authors, which is composed of two large, chromite-rich massifs, the Mayari Cristal and Moa Baracoa.
Journal ArticleDOI
Chromitites in ophiolites: How, where, when, why? Part II. The crystallization of chromitites
José María González-Jiménez,William L. Griffin,Joaquín A. Proenza,Fernando Gervilla,Suzanne Y. O'Reilly,Mehmet Akbulut,Norman J. Pearson,Shoji Arai +7 more
TL;DR: A review of previous work relevant to the formation of concentrations of chromite in peridotites from ophiolitic (s.l.) sequences highlights some of the key problems in understanding the complex processes involved as discussed by the authors.
Journal ArticleDOI
High-Cr and high-Al chromitites from the Sagua de Tánamo district, Mayarí-Cristal ophiolitic massif (eastern Cuba): Constraints on their origin from mineralogy and geochemistry of chromian spinel and platinum-group elements
José María González-Jiménez,Joaquín A. Proenza,Fernando Gervilla,J.C. Melgarejo,J. A. Blanco-Moreno,R. Ruiz-Sánchez,William L. Griffin +6 more
TL;DR: In this article, a large number of chromitite bodies of variable sizes are hosted in dunite-harzburgite of the small (b3 km) mining district of Sagua de Tanamo, in the Mayari-Cristal ophiolitic massif, eastern of Cuba.
Journal ArticleDOI
Distribution of platinum-Group elements and Os isotopes in chromite ores from Mayarí-Baracoa Ophiolitic Belt (eastern Cuba).
Fernando Gervilla,Joaquín A. Proenza,Robert Frei,José María González-Jiménez,Carlos J. Garrido,J.C. Melgarejo,Anders Meibom,R. Díaz-Martínez,W. Lavaut +8 more
TL;DR: In this article, the chemistry of chromite ore is very variable, ranging from high Al (Cr#=0.43-0.55) to high Cr (Cr # = 0.60 -0.83) compositions.
Journal ArticleDOI
Petrogenesis of highly depleted peridotites and gabbroic rocks from the Mayarí-Baracoa Ophiolitic Belt (Eastern Cuba).
Claudio Marchesi,Carlos J. Garrido,Marguerite Godard,Joaquín A. Proenza,Fernando Gervilla,Jesús Blanco-Moreno +5 more
TL;DR: In this article, it was shown that peridotites are very refractory in terms of modal composition, whole rock major element and HREE contents implying that they are residues after high degrees (20-30%) of partial melting.
