The Famatinian is a segment of the Ordovician Terra Australis accretionary orogen that stretched along the SW Margin of Gondwana from Australia to Colombia. The present knowledge of this orogenic segment still is incomplete. We present geochemistry a

Late Cambrian – Early Ordovician magmatism in the Sierra de Pie de Palo, Sierras Pampeanas (Argentina): implications for the early evolution of the proto-Andean margin of Gondwana

The Sierra de Pie de Palo, in the Argentinean Sierras Pampeanas (Andean foreland), consists of a Mesoproterozoic basement and an Ediacaran-upper Cambrian sedimentary cover that underwent folding, thrusting and metamorphism during the Ordovician Famat

The Sierra de Guasayán (Eastern Sierras Pampeanas, Argentina) is formed by low to medium grade metamorphic rocks intruded by Cambrian metaluminous (La Soledad quartz-diorite), slightly peraluminous (Guasayán, El Escondido and El Martirizado granodi

O–H–Sr–Nd isotope constraints on the origin of the Famatinian magmatic arc, NW Argentina
Autor: C. Recio, Carmen Galindo, Carlos W. Rapela, César Casquet, Pablo H. Alasino, Robert J. Pankhurst, Mariano A. Larrovere, Edgardo G. Baldo, Carlos D. Ramacciotti, Juan A. Dahlquist
We report a study of whole-rock O–H–Sr–Nd isotopes of Ordovician igneous and metamorphic rocks exposed at different crustal palaeodepths along c. 750 km in the Sierras Pampeanas, NW Argentina. The isotope compositions preserved in the intermedi

The Late Paleozoic Ice Age (LPIA) has been well recorded in the uppermost Mississippian?Pennsylvanian of Gondwana. Nevertheless, little is known about the temporal and geographic dynamics, particularly during the early Mississippian. We report on exc

Petrogenesis of the F-rich peraluminous A-type granites: an example from the devonian Achala batholith (Characato Suite), Sierras Pampeanas, Argentina

The Characato suite (Achala batholith, Sierras Pampeanas, Argentina), consists of at least six granitic facies with affinities of F-rich moderately to strongly peraluminous A-type granites. The two more extensive facies (Facies 1 and 2) and a minor o

Whereas north of 33°S Devonian calcalkaline magmatism is notably absent, a Devonian arc is well developed to the south of 33°S. The Carrizalito, Pampa de los Avestruces, and Papagayos plutons are l...
