Reassessment of the volume of the Las Aguilas mafic-ultramafic intrusives, San Luis, Argentina, based on an alternative geophysical model
(Pergamon-Elsevier Science Ltd, 2011-10)
In the Sierra de San Luis, Central Argentina, a belt of small and discontinuous lenses of mafic-ultramafic rocks intrude a polydeformed basement and are thought to be the cause of a local increase of the metamorphic grade ...
Geochemistry and Sm–Nd isotope systematics of mafic-ultramafic rocks from the Babina and Mauranipur greenstone belts, Bundelkhand Craton, India: Implications for tectonic setting and Paleoarchean mantle evolution
(Elsevier Science, 2019-04)
The Paleoarchean geodynamical evolution of the Bundelkhand Craton is discussed based on the geochemistry (major, trace and rare earth elements) and Sm–Nd isotope systematic of mafic-ultramafic rocks from volcano-sedimentary ...
Sr and Nd isotopic geochemistry of the early ultramafic-mafic rocks of the Mako bimodal volcanic belt of the Kedougou-Kenieba inlier (Senegal)
(SPRINGER HEIDELBERG, 2010)
The Mako bimodal volcanic belt of the Kedougou-Kenieba inlier is composed of volcanic basalts and peridotites interbedded by quartzites and limestones intruded by different generations of granitoids. The early volcanic ...
Chrome spinels from the Las Águilas mafic-ultramafic intrusion, San Luis Province, Argentina
(E Schweizerbartsche Verlags, 2006-12)
Two groups of spinel are documented from the mafic-ultramafic rocks of Las Águilas, San Luis Province, Central Argentina. Both spinel types have chromium-aluminum rich cores. However, type I spinel cores are surrounded by ...
Ultramafic complexes and associated mineral deposits in the Precambrian of eastern Minas Gerais, Brazil
(Springer, 1985-10-01)
Based on field work, prospection and petrographic studies ultramafic complexes and their mineral deposits from eastern Minas Gerais in southeastern Brazil are generally outlined to form a basis for future investigations ...
Petrology, geochemistry and mineralization of the Las Águilas and Virorco mafic-ultramafic bodies, San Luis Province, Argentina
(Springer, 2012-11-21)
The layered mafic?ultramafic rocks in the Sierras de San Luis, Argentina (Las Águilas, Las Higueras and Virorco), constitute a 3?5-km-wide belt that extends over 100 km from NE to SW. They carry a sulphide mineralization ...
Deformational evolution of the Vale do Jacurici rocks: implications for the structuration of the mafic-ultramafic chromite bodiesEvolução deformacional das rochas do Vale do Jacurici: implicações para a estruturação dos corpos cromitíferos máfico-ultramáficos
