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

Ramacciotti, Carlos ; Casquet, César ; Baldo, Edgardo G. ; Galindo Francisco, Mª del Carmen ; Pankhurst, Robert J. ; Verdecchia, Sebastián Osvaldo ; Rapela, Carlos W. ; Fanning, C.M. | Springer Verlag | 2018-10The Western Sierras Pampeanas (WSP) of Argentina record a protracted geological history from the Mesoproterozoic assembly of the Rodinia supercontinent to the early Paleozoic tectonic evolution of SW Gondwana. Two well-known orogenies took place[...]texto impreso
Rapela, Carlos W. ; Pankhurst, R.J. ; Casquet, César ; Fanning, C.M. ; Galindo Francisco, Mª del Carmen ; Baldo, Edgardo G. | Sociedad Geológica de España | 2005The Neoproterozoic Difunta Correa meta-sedimentary sequence (DCSS) of Western Sierras Pampeanas is a cover to a rejuvenated Grenvillian basement. The Western Sierras Pampeanas are allegedly part of the exotic Precordillera Terrane, which was acc[...]texto impreso
Baldo, Edgardo G. ; Casquet, César ; Galindo Francisco, Mª del Carmen | Sociedad Geológica de España | 1998The Sierra de Pie de Palo belongs to the Western Sierras Pampeanas. Although still poorly known in detail, the sierra consists of a relatively autochthonous sequence of shelf sediments metamorphosed to low grade (the Caucete Group) and an alloch[...]texto impreso
Casquet, César ; Pankhurst, R.J. ; Galindo Francisco, Mª del Carmen ; Rapela, Carlos W. ; Fanning, C.M. ; Baldo, Edgardo G. ; Dahlquist, Juan A. ; González Casado, José Manuel ; Colombo, F. | Elsevier Science B.V., Amsterdam | 2008A deformed ca. 570Ma syenite–carbonatite body is reported from a Grenville-age (1.0–1.2 Ga) terrane in the Sierra de Maz, one of theWestern Sierras Pampeanas of Argentina. This is the first recognition of such a rock assemblage in the basement o[...]texto impreso

Segovia Díaz, Emilio ; Casquet, César ; Baldo, Edgardo G. ; Galindo Francisco, Mª del Carmen | Sociedad Geológica de España | 2012En las sierras de Maz y El Espinal (La Rioja,Argentina) el basamento polimetamórfico (terreno Maz) registra tres eventos metamórficos: M1 y M2, grenvillianos (entre 1,05 - 1,2 Ga); M3, famatiniano (470 a 430 Ma). En el Dominio de Ramaditas de la[...]texto impreso
Rapela, C. W. ; Pankhurst, Robert J. ; Casquet, César ; Baldo, Edgardo G. | Geological Society of America | 1998From a detailed study of a 500 km transect in the Sierras Pampeanas, central-west Argentina, two pre-Silurian tectono-magmatic episodes are recognized and defined, each culminating n micro-continental collisions against the proto-Andean margin o[...]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.

They are particularly abundant within or near the worldwide Grenvillian mobile belt (1.0-1.2Ga), which resulted from[...]
