Las vulcanitas de la formación San Luis (Sierra de San Luis, Argentina). Nueva edad (SHRIMP) y geoquímica isotópica (Sr y Nd)
(2014)
La Formación San Luis, de edad aún imprecisa, aflora en dos bandas de dirección NNE-SSO en la Sierra del
mismo nombre. En la banda occidental, en el sector comprendido entre el dique de La Florida y el Paso Santo
Domingo, ...
The geological setting of Carboniferous magmatism in the proto-Andean margin of Gondwana, Sierra Pampeanas, Argentina
(2014)
Our petrogenetic understanding of the Carboniferous granites of the Sierras Pampeanas has
improved in recent years, but their geodynamic setting is still not well constrained. Domeier and
Torsvik (2014) affirm that there ...
Edad U/Pb SHRIMP en circones detríticos al sureste de Pie de palo, San Juan, Argentina: Evidencias de sedimentación y magmatismo paleozoico en las Sierras Pampeanas Occidentales
(2014)
La Sierra de Pie de Palo consiste de un sistema de corrimientos de vergencia oeste, cuyas láminas están
compuestas por un basamento mesoproterozoico (Casquet et al., 2001; Vujovich et al., 2004; Rapela et al.,
2010) ...
The relationships between pre- to syn-Pampean orogeny metasedimentary rocks in the Eastern sierras Pampeanas (Argentina)
(2014)
Two series of pre-to syn-Pampean orogeny metasedimentary rocks can be distinguished in
the Sierras Pampeanas on the basis of U-Pb SHRIMP detrital zircon ages. On one hand the
Ancaján series consists of meta-siliciclastic ...
Early Paleozoic construction of southwest Gondwana: evidence from detrital zircons in the Sierras Pampeanas
(2014)
Basement exposures in the Sierras Pampeanas at 26º–33ºS give a unique opportunity to compare
paleo-sediment sources along a significant stretch of the Andean foreland. To this end we have
studied a large number of ...
The continental assembly of SW Gondwana (Ediacaran to Cambrian): a synthesis
(2014)
SW Gondwana resulted from complex interplay between continental amalgamation and
dispersal between ~ 650 and 490 Ma. The main cratons involved were Laurentia, Amazonia–
MARA (Proterozoic Maz–Arequipa–Rio Apa, Casquet et ...
