Sr and Nd isotope composition of the metamorphic, sedimentary and ultramafic xenoliths of Lanzarote (Canary Islands): Implications for magma sources
(ELSEVIER SCIENCE BV, 2010)
The lavas produced by the Timanfaya eruption of 1730-1736 (Lanzarote, Canary Islands) contain a great many sedimentary and metamorphic (metasedimentary), and mafic and ultramafic plutonic xenoliths. Among the metamorphosed ...
Origin of the DUPAL anomaly in mantle xenoliths of Patagonia (Argentina) and geodynamic consequences
(Elsevier Science, 2016-04)
The sub-continental lithospheric mantle of South America has been known for some time to carry the DUPAL isotope anomaly as seen in volcanics from the Paraná volcanic province. However, this has not allowed discriminating ...
Upper Cambrian carbonate sequences of the Argentine Precordillera and the Steptoean C-Isotope positive excursion (SPICE)
(Elsevier Science, 2008-07)
Carbon and Sr-isotope profiles in Upper Cambrian platformal carbonate Formations in the Precordillera, western Argentina (Zonda, La Flecha and La Silla Formations), were constructed for three representative sections: (a) ...
Slab-derived components in the subcontinental lithospheric mantle beneath Chilean Patagonia: Geochemistry and Sr–Nd–Pb isotopes of mantle xenoliths and host basalt
(Elsevier, 2017)
In subduction zones, ultramafic xenoliths hosted in alkaline basalts can yield significant information about
the role of potential slab-derived components in the subcontinental lithospheric mantle (SCLM). Chemical ...
The somuncura large igneous province in Patagonia: Interaction of a transient mantle thermal anomaly with a subducting slab
(Oxford University Press, 2007-12)
The Oligo-Miocene Somuncura province is the largest (∼55 000 km2) back-arc mafic volcanic field in Patagonia, and one of Earth's largest with no clear link to a hotspot or major extension. Major and trace element and ...
Geochemistry and Sr, Nd, Pb isotopic composition of the Central Atlantic Magmatic Province (CAMP) in Guyana and Guinea
(ELSEVIER SCIENCE BV, 2005-06)
The Central Atlantic Magmatic Province (CAMP) is one of the largest igneous provinces on Earth, extending more than 5000 km north to south, on both sides of the Atlantic Ocean. Its emplacement occurred about 200 Ma ago, ...
Peraluminous Grenvillian TTG in the Sierra de Pie de Palo, Western Sierras Pampeanas, Argentina: Petrology, geochronology, geochemistry and petrogenetic implications
(ELSEVIER, 2010)
Combined petrological, geochemical, isotopic and geochronological data shed light on the origin and evolution of a peraluminous garnet-bearing two-mica granitoid (El Tigre Granitoid: ETG) cropping out in southwestern Sierra ...
