Abstract A detailed study of the pre-Silurian geology Sierras de Córdoba, Eastern Pampeanas, is used to define sequence magmatic and metamorphic events during Pampean orogeny. This primarily involved Early Mid-Cambrian subduction terrane collision at western margin Gondwana amalgamation super-continent. Evidence for this based principally on new information concerning (a) regional mapping field relations, (b) analysis structures, deformational history meta-morphic evolution (c) geochronology...

The role played by Paleoproterozoic cratons in southern South America from the Mesoproterozoic to Early Cambrian is reconsidered here. This period involved protracted continental amalgamation that led formation of supercontinent Rodinia, followed Neoproterozoic break-up, with consequent opening Clymene and Iapetus oceans, finally re-assembly as Gondwana through complex oblique collisions Late Cambrian. evidence for this based mainly on a combination precise U-Pb SHRMP dating radiogenic...

Abstract Magnetite-(apatite) ore deposits are interpreted as being formed by the crystallization of iron-rich ultrabasic melts, dominantly generated interaction silicate melts with oxidized P-F-SO 4 -bearing sedimentary rocks. This hypothesis is supported geologic evidence, experimental studies, numerical modeling, stable and radiogenic isotope geochemistry, mineralogy, melt- mineral-inclusion data. Assimilation crustal rocks during ascent promotes separation from a magma Fe-rich, Si-Al-poor...
New U–Pb radiometric dates for K-bentonite horizons within the Lower Cambrian to Middle Ordovician platform carbonates from Precordillera terrane of NW Argentina provide further constraints on models allochthonous or parautochthonous accretion this terrane. Two layers Talacasto section yield indistinguishable sensitive high-resolution ion microprobe (SHRIMP) zircon 469.5 ± 3.2 Ma and 470.1 3.3 respectively. These are uncertainty SHRIMP date 468.3 3.4 a porphyritic rhyolite Famatinian...
