ABSTRACT Sixty-two 14 C dates are analyzed in combination with a recently established local floating tree-ring sequence for the Early Neolithic site of La Draga (Banyoles, northeast Iberian Peninsula). Archaeological data, radiometric and dendrochronological dates, as well sedimentary micro-stratigraphical information used to build Bayesian chronological model, using ChronoModel 2.0 OxCal 4.4 c...

Metrichia is assigned to the Ochrotrichiinae, a group of almost exclusively Neotropical microcaddisflies. Metrichia comprises over 100 described species and, despite its diversity, only one species has been described from Brazil so far. In this paper, we provide descriptions for 20 new species from 8 Brazilian states: M. acuminata sp. nov., M. azul sp. nov., M. bonita sp. nov., M. bracui sp. no...

In this study, we present a subannual–biannual-resolved (0.9–2 years) ASM intensity record spanning from 11.6 to 10.0 ka BP (before 1950 AD) inferred 230Th-dated travertine δ18O at Zhangjia Ravine on the eastern margin of Tibetan Plateau. The ZJG-1 sequence is characterized by high-frequency fluctuations decadal centennial scales. Fluctuating between −11.15‰ and −14.78‰ over sequence, fluctuati...

In the Zambales ophiolite range, terrestrial serpentinizing fluid seeps host diverse microbial assemblages. The fluids fall within the profile of Ca(2+)-OH(-)-type waters, indicative of active serpentinization, and are low in dissolved inorganic carbon (DIC) (<0.5 ppm). Influx of atmospheric carbon dioxide (CO2) affects the solubility of calcium carbonate as distance from the source increases, ...

Abstract Cyanobacteria are considered to be among the first microorganisms settle in hot springs where they form a favourable environment for further biological establishment. Nevertheless, exact pioneer species and how early start participating biomineralisation processes remain unknown. The aim of present study was twofold, that is, identify (i.e. Aedipsos area, Greece) record their processes...

Understanding carbon dioxide (CO2) reservoir to surface migration is crucial successful capture and sequestration approaches; especially fault/reservoir interactions under injection pressure. Through seismic imaging, we explore regolith shallow stratigraphy across the Little Grand Wash fault. The presence of natural CO2 seeps, travertine tufa deposits confirm modern ancient fault-controlled lea...
