Depositional age models in lacustrine systems from zircon and carbonate U‐Pb geochronology
Abstract The Yacoraite Formation (Salta rift, Argentina) consists of Maastrichtian–Danian lacustrine carbonate and siliciclastic deposits with interbedded volcanic ash layers, organized in four third‐order stratigraphic sequences. It offers the exceptional opportunity to jointly apply in situ zircon and carbonate U‐Pb geochronology that resulted in two

Abstract We report results from geoarchaeological investigations at Cuncaicha rock shelter (4480 m above sea level) in the high Andes of southern Peru. Using field observations, geomorphological, micromorphological, micro‐Fourier transform infrared spectroscopy, Bayesian modeling of radiocarbon ages, and archaeological data, we analyzed the entire ...

Rainforest catchment dominated by quick near‐surface runoff generation. Tracer‐aided modelling revealed transit times and water flux ages of less than 3 months old. Climate variability exerts a limited control on mixing of waters. Young water ages result from quick runoff generation with limited mixing, high rainfall volumes and groundwater losses ...

Abstract Authigenic clays are an important control on reservoir quality in lacustrine carbonates but remain challenging to predict. Lacustrine depositional systems respond to climatic variations in rainfall, surface runoff and groundwater input, and evaporation, and result in rapid and frequent changes in lake volume; this is expressed through changing

Characterization of Phenotypic Diversity of Feijoa Fruits of Germplasm Accessions in Brazil
Core Ideas Feijoa fruit combine unique flavor and medicinal properties. The Brazilian feijoa collection exhibit high variability in fruit traits. Years was the major effect to all fruit trait phenotype in south of Brazil. The aim of the present work was to physicochemically characterize the fruits of accessions of feijoa [Acca sellowiana (O.

Summary This study analyses and compares the genetic signatures of anagenetic and cladogenetic speciation in six species of the genus Robinsonia (Asteraceae, Senecioneae), endemic to the Juan Fernández Islands, Chile. Population genetic structure was analyzed by amplified fragment length polymorphism (AFLP) and microsatellite (simple sequence repeat ...

We present data on carbon and nitrogen isotopic composition of human bones from Tolombón (Calchaqui Valley, Salta) and Esquina de Huajra (Quebrada de Humahuaca, Jujuy) sites located in Northwest Argentina (NWA). Both are complex archaeological residential settlements ascribed to the Regional Development Period (ca.
