Galindo Francisco, Mª del Carmen ; Pankhurst, R.J. ; Casquet, César ; Coniglio, Jorge ; Baldo, Edgardo G. ; Rapela, Carlos W. ; Saavedra, Julio | Taylor & Francis | 1997Fluorite mineralization at the La Nueva and Bubu mines yields Sm-Nd ages of 131 ± 22 and 117 ± 26 Ma, respectively. Thus, the mineralization most probably is related to a late Gondwanian (Lower Cretaceous) extensional and magmatic event that aff[...]texto impreso
Alasino, Pablo H. ; Dahlquist, Juan A. ; Galindo Francisco, Mª del Carmen ; Casquet, César ; Saavedra, Julio | Springer Science Business Media | 2010The La Costa pluton in the Sierra de Velasco (NW Argentina) consists of S-type granitoids that can be grouped into three igneous facies: the alkali-rich Santa Cruz facies (SCF, SiO2 *67 wt%) distinguished by the presence of andalusite and Na- an[...]texto impreso
Galindo Francisco, Mª del Carmen ; Baldo, Edgardo G. ; Pankhurst, R.J. ; Casquet, César ; Rapela, Carlos W. ; Saavedra, Julio | Sociedad Geológica de España | 1996The fluorite mineralization from the La Nueva Mine, has a Sm-Nd age of 130 ± 19 Ma, and thus must be related to the Lower Cretaceous late-Gondwanic extensional and magmatic event that affected the Sierras Pampeanas Basement of Argentina.

Casquet, César ; Galindo Francisco, Mª del Carmen ; Rapela, Carlos W. ; Pankhurst, R.J. ; Baldo, Edgardo G. ; Dahlquist, Juan A. ; Fanning, C.M. ; González Casado, José Manuel ; Saavedra, Julio | Instituto Geológico y Minero de España | 2005Massif-type anorthosites are igneous complexes that consist for the most part of anorthosite, a plagioclase- rich plutonic rock. They are particularly abundant within or near the worldwide Grenvillian mobile belt (1.0-1.2Ga), which resulted from[...]texto impreso
Casquet, César ; Pankhurst, R.J. ; Rapela, Carlos W. ; Galindo Francisco, Mª del Carmen ; Dahlquist, Juan A. ; Baldo, Edgardo G. ; Saavedra, Julio ; González Casado, José Manuel ; Fanning, C.M. | Geological Society of London. | 2004-01We report the discovery of massif-type anorthosites in the Andean basement of the Western Sierras Pampeanas of Argentina. U–Pb zircon dating (by sensitive high-resolution ion microprobe) of a cogenetic gabbronorite dyke yields ages of 1070 ± 41 [...]texto impreso
Casquet, César ; Rapela, Carlos W. ; Pankhurst, R.J. ; Baldo, Edgardo G. ; Galindo Francisco, Mª del Carmen ; Fanning, C.M. ; Dahlquist, Juan A. ; Saavedra, Julio | Elsevier B.V. | 2012The role played by Paleoproterozoic cratons in southern South America from the Mesoproterozoic to the Early Cambrian is reconsidered here. This period involved protracted continental amalgamation that led to formation of the supercontinent Rodin[...]texto impreso
Casquet, César ; Baldo, Edgardo G. ; Pankhurst, R.J. ; Rapela, Carlos W. ; Galindo Francisco, Mª del Carmen ; Fanning, C.M. ; Saavedra, Julio | Geological Society of America | 2001New data suggest that the eastern margin of the Argentine Precordillera terrane comprises Grenvillian basement and a sedimentary cover derived from it that were together affected by Middle Ordovician deformation and metamorphism during accretion[...]texto impreso

Dahlquist, Juan A. ; Galindo Francisco, Mª del Carmen ; Pankhurst, R.J. ; Rapela, Carlos W. ; Alasino, Pablo H. ; Saavedra, Julio ; Fanning, C.M. | Elsevier Science B.V., Amsterdam | 1995Garnet is an uncommon accessory mineral in igneous rocks but is petrologically significant. The Peñón Rosado granite (469± 4Ma) at Cerro Asperecito is an S-type granite that contains an unusual amount of magmatic garnet. Combined petrology, chem[...]texto impreso
