Se presentan los resultados obtenidos en el estudio isotopico de rocas del basamento igneo-metamorfico Andes expuesto Argentina, aproximadamente a 40°S, las provincias Neuquen y Rio Negro. Fueron utilizadas metodologias isotopicas, para obtener informacion sobre la edad emplazamiento cuerpos igneos deformados ductilmente (U-Pb circones), tiempo enfriamiento luego procesos metamorficos que modelaron este (K-Ar micas; U-Pb titanita) historia cortical involucrada (Sm-Nd roca total).

The superposition of two orogenies during the evolution Paleoproterozoic Tandilia Belt, Argentina, produced complex geological structures in granitic-gneissic-migmatitic Buenos Aires Complex. Ion microprobe (SHRIMP II) dating 61 spots 56 zircon crystals from 10 rock samples shows tectonic activity related to accretionary Encantadas orogeny 2.25-2.12 Ga, although a major overprint collisional Camboriú 2.10-2.08 Ga is also recognized. Only one age Neoarchean. Two peaks for Belt are ~2.16 and...
Abstract Ordovician K-bentonites have now been recorded from >20 localities in the vicinity of Argentine Precordillera. Most occur eastern thrust belts, San Juan Limestone and overlying Gualcamayo Formation, but a few ash beds are known also central belts. The oldest middle Arenig I. victoriae lunatus graptolite ( Oe. evae conodont) Zone, youngest Llanvirn P. elegans suecicus ) Zone. Mineralogical characteristics, typical other K-bentonites, include matrix illite/smectite mixed-layer clay...
Bed-by-bed collecting of the La Chilca Formation at Talacasto, San Juan, Argentina has revealed a sequence spanning Ordovician–Silurian boundary, and recognition following graptolite zones: Glyptograptus persculptus , probable Parakidograptus acuminatus possible Atavograptus. The Talacasto section thus allows closest definition boundary in South America. shales are 3.65 m thick, rich graptolites, have allowed us to recognize for first time America several stratigraphically important forms:...
