Tornos Arroyo, Fernando ; Delgado Huertas, Antonio ; Casquet, César ; Galindo Francisco, Mª del Carmen | Springer Science Business Media | 2000The Eastern Iberian Central System has abundant ore showings hosted by a wide variety of hydrothermal rocks; they include Sn-W, Fe and Zn-(W) calcic and magnesian skarns, shear zone- and episyenitehosted Cu-Zn-Sn-W orebodies, Cu-W-Sn greisens an[...]texto impreso
Galindo Francisco, Mª del Carmen ; Casquet, César ; Tornos Arroyo, Fernando | Sociedad Geológica de España | 2010Episodic hydrothermal alterations in the Sierra de Guadarrama took place between ca. 300 Ma and 10 Ma. New K-Ar ages for hydrothermal minerals have been obtained that along with previous data allow to better constrain the late- to post-Variscan [...]texto impreso
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
Zucchiatti, A. ; Climent-Font, A. ; Gutiérrez-Neira, P. C. ; Montero-Ruiz, I. ; Fuenlabrada Pérez, José Manuel ; Galindo Francisco, Mª del Carmen | Elsevier | 2018-06Analytical techniques have been used to implement the archaeological information from surface surveys. We have shown that the compositional comparison of amorphous samples, e.g. glass, can provide important chronological information when compare[...]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
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
Galindo Francisco, Mª del Carmen ; Casquet, César | Seminario de Estudos Galegos. Area de Xeoloxía e Minería ; Instituto Universitario de Xeoloxía "Isidro Parga Pondal" | 1985En el Complejo Plutónico de Táliga-Barcarrota se distinguen dos tendencias geoquimicas: la primera de ellas corresponde a una"asociación peralumínica" representada por los granitos biotíticos de Táliga, la segunda de caracter "cafémico-subalcali[...]texto impreso
Alasino, Pablo H. ; Dahlquist, Juan A. ; Galindo Francisco, Mª del Carmen ; Casquet, César | Sociedad Española de Mineralogía | 2006En este trabajo se presentan dos casos de cordieritas de comprobado origen ígneo y metamórfico en el plutón de Cerro Toro (Sierras Pampeanas, Argentina). A partir de comparaciones petrográficas y de química mineral entre dichas cordieritas, se c[...]texto impreso
Dahlquist, Juan Andrés ; Galindo Francisco, Mª del Carmen ; Morales Cámera, Matías M. ; Moreno, Juan A. ; Alasino, Pablo H. ; Basei, Miguel A.S. ; Macchioli Grande, Marcos | Elsevier | 2020-06We report new whole-rock Nd and Sr isotope data for two strongly peraluminous and one slightly peraluminous Carboniferous A-type granitic plutons in the eastern Sierras Pampeanas of Argentina. Our study also integrates previous petrological and [...]texto impreso
Galindo Francisco, Mª del Carmen ; Huertas Coronel, María José ; Casquet, César | Sociedad Geológica de España | 1994Two calcalkaline granite porphyries, an E-W and a N-S trending one, and three monzonitic dykes striking NE-SW, have been dated. For the first dyke a whole rock Rb-Sr isochrone age of 296±3 Ma, i.e. Upper Carboniferous, is obtained. However, the [...]texto impreso
Antón López, Loreto ; Muñoz Martín, Alfonso ; Vicente Muñoz, Gerardo de ; Galindo Francisco, Mª del Carmen | Sociedad Geológica de España. | 2004The present paper deals with K-Ar absolute dating performed on three fault gouges structures selected across the geological structure known as the Domo del Tormes (Zamora-Salamanca, Spain). The dating performed on five clay samples, with grain s[...]texto impreso
Galindo Francisco, Mª del Carmen ; Darbishyre, D.P.F. ; Tornos Arroyo, Fernando ; Casquet, César | Sociedad Geológica de España | 1993Sm-Nd dating of F-Ba (Pb-Zn) veins enclosed in adamellites of the Spanish Central System suggests an age of 752±25 M.a. (Late jurassic) for this hydrothermal stage. This age supports an unconformity-related origin for this style of mineralizatio[...]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
Galindo Francisco, Mª del Carmen ; Portugal Ferreira, Martín R. ; Casquet, César ; Priem, H.N.A. | Sociedad Geológica de España | 1990The Plutonic Complex of Táliga-Barcarrota crops out in the core of the Olivenza-Monesterio anticline, where it intrudes the Upper Precambrian and Lower Cambrian metasediments. As this Complex is made of a) the Circular Pluton of Barcarrota, wher[...]
