Mafic dykes at the southwestern margin of Eastern Ghats belt: Evidence of rifting and collision
(INDIAN ACAD SCIENCES, 2010)
The southwestern margin of the Eastern Ghats Belt characteristically exposes mafic dykes intruding massif-type charnockites. Dykes of olivine basalt of alkaline composition have characteristic trace element signatures ...
The temporal evolution of back-arc magmas from the Auca Mahuida shield volcano (Payenia Volcanic Province, Argentina)
(Elsevier Science, 2016-09)
In order to better constrain the temporal volcanic activity of the back-arc context in Payenia Volcanic Province (PVP, Argentina),we present newK?Ar dating, petrographic data,major and trace elements from23 samples collected ...
Geochemical constraints on the petrogenesis of Triassic alkaline basalts of Sierra de Valle Fértil, Western Sierras Pampeanas, Argentina: implications for their origin, evolution and tectonic setting
(Pergamon-Elsevier Science Ltd, 2019-11)
The first geochemical and Sr-Nd isotope data of a series of Triassic basaltic rocks from Sierra de Valle Fértil, Western Sierras Pampeanas, Argentina, are herein presented. The mafic rocks are the result of continental ...
Payenia volcanic province, southern Mendoza, Argentina: OIB mantle upwelling in a backarc environment
(Elsevier Science, 2013-06)
The Pleistocene to Holocene Payenia volcanic province is a backarc region of 60,000 km2 in Mendoza, Argentina, which is dominated by transitional to alkaline basalts and trachybasalts. We present major and trace element ...
Basic magmatism in northeastern Puna, Argentina: Chemical composition and tectonic setting in the Ordovician back-arc
(Pergamon-Elsevier Science Ltd, 2009-12)
Two main groups of basic rocks, representative of the bimodal Ordovician magmatism of the northeastern Puna (22-24°S, 66°30'-65°40'W) were revisited on the basis of new geological, petrographic and geochemical data. One ...
Petrografía y geoquímica de la Basanita El Retamo: nueva evidencia del magmatismo triásico en la Sierra de Valle Fértil, provincia de San JuanPetrography and geochemistry of the El Retamo basanite: new evidence of Triassic magmatism in Sierra de Valle Fértil, province of San Juan
(Asociación Geológica Argentina, 2019-12)
La Basanita El Retamo, localizada en el sector norte de la Sierra de Valle Fértil, corresponde a una nueva evidencia del vulcanismo alcalino de edad triásica para esta región. Es interpretada como el remanente de una colada ...
The Río Cañete Basin: Implications for the Mesozoic geoynamic evolution of the Peruvian margin
(8th International Symposium on Andean Geodynamics (ISAG)EC, 2019-09)
The evolution of the Río Cañete Basin provides a robust geodynamic model that can be extrapolated throughout the Peruvian margin. Transtensional crustal attenuation during the Jurassic early stages of Andean oblique ...
