La sierra de Velasco en el noroeste argentino. Un ejemplo de magmatismo polifase en el margen de Gondwana.
The Sierra de Velasco is formed of large plutons that are related to each other by intrusive contacts and separated by generally aligned deformation zones. The plutons are composed of calc-alkaline, syn-, late- and post-kinematic granitoids of different ages and intrusion levels. They are grouped in three large batholiths: Aimogasta, Bazán and Patquía. On the northeastern flank, the metamorphic country rock is represented by micaschists, phyllites and quartzites with hornfels (La Cébila Formation), to the north by tonalitic porphyries that in all cases demonstrate a shallow level of the granitoid intrusions. Shape of the plutons, as well as structural characters and grade of deformation indicate that the intrusive sequences began in Ordovician times and culminated in the Carboniferous, with deformation periods during Silurian and Devonian times. © 2007 E. Schweizerbart'sche Verlagsbuchhandlug.La Sierra de Velasco es un extenso afloramiento predominantemente granítico, integrado por plutones calco-alcalinos, sin-, tardío- a post-tectónicos, con edades diferentes y relacionados entre sí tanto a través de fajas de deformación, como por relaciones intrusivas. Los plutones se agrupan en los batolitos: Aimogasta, Bazán, y Patquía. Las rocas metamórficas de caja están representadas por micacitas, filitas y cuarcitas, con corneanas, sobre el flanco nororiental, y pórfiros tonalíticos en el extremo norte de la sierra, que evidencian el emplazamiento somero de los granitos. Las formas de los plutones, así como los caracteres estructurales y grados de deformación, indican que las secuencias graníticas se habrían iniciado en el Ordovícico y culminado en el Carbonífero, con edades de deformación en el Siluro-Devónico.Fil: Toselli, Alejandro Jose.

Cambro-Ordovician age of a metagabbro from the Wildschonau ophiolite complex, Greywacke Supergroup (Eastern Alps, Austria): A U-Pb SHRIMP study
Lower Carboniferous post-orogenic granites in central-eastern Sierra de Velasco, Sierras Pampeanas, Argentina: U-Pb monazite geochronology, geochemistry and Sr-Nd isotopes
The central-eastern part of the Sierra de Velasco (Sierras Pampeanas, NW Argentina) is formed by the large Huaco (40 x 30 km) and Sanagasta (25 x 15 km) granite massifs and the small La Chinchilla stock (2 x 2 km). The larger granites intrude into Ordovician metagranitoids and crosscut Devonian (?) mylonitic shear zones, whereas the small stock sharply intrudes into the Huaco granite. The two voluminous granites are biotitic-muscovitic and biotitic porphyritic syeno- to monzogranites. They contain small and rounded tonalitic and quartz-dioritic mafic microgranular enclaves. The small stock is an equigranular, zinnwaldite- and fluorite-bearing monzogranite. The studied granites are silica-rich (SiO2 > 70%), potassium-rich (K2O > 4%), ferroan, alkali-calcic to slightly calk-alkalic, and moderately to weakly peraluminous (A/CNK = 1.06-1.18 Huaco granite; 1.01-1.09 Sanagasta granite; 1.05-1.06 La Chinchilla stock). They have moderate to strong enrichments in several LIL (Li, Rb, Cs) and HFS (Nb, Ta, Y, Th, U) elements, and low Sr, Ba and Eu contents. U-Pb monazite age determinations indicate Lower Carboniferous crystallization ages: 350-358 Ma for the Huaco granite, 352.7 ± 1.4 Ma for the Sanagasta granite and 344.5 ± 1.4 Ma for the La Chinchilla stock. The larger granites have similar eNd values between ?2.1 and ?4.3, whereas the younger stock has higher eNd of ?0.6 to ?1.4, roughly comparable to the values obtained for the Carboniferous San Blas granite (?1.4 to ?1.7), located in the north of the sierra. The Huaco and Sanagasta granites have a mainly crustal source, but with some participation of a more primitive, possibly mantle-derived, component. The main crustal component can be attributed to Ordovician peraluminous metagranitoids. The La Chinchilla stock derives from a more primitive source, suggesting an increase with time in the participation of the primitive component during magma genesis. The studied granites were generated during a post-orogenic period in a within-plate setting, possibly as a response to the collapse of the previous Famatinian orogen, extension of the crust and mantle upwelling. They are part of the group of Middle Devonian-Lower Carboniferous granites of the Sierras Pampeanas. The distribution and U-Pb ages of these granites suggests a northward arc-parallel migration of this mainly post-orogenic magmatism with time.Fil: Grosse, Pablo.
