Abstract Sedimentological and hydrochemical parameters of the River Piedra (north‐east Spain) were monitored every six months (from 1999 to 2012) at 24 sites, which tablets installed all along river. The river water is HCO 3 –SO 4 –Ca type notably influenced by inputs from upstream karstic springs. Tufa deposition was first detected 8 km downstream these springs greatly increased there, primarily steeper stretch (i.e. within Monasterio de Natural Park); then, decreased through most stretch,...
The drainage area of the Iberian Ranges (NE Spain) houses one most extensive Quaternary fluvial tufaceous records in Europe. In this study, tufa deposits Añamaza, Mesa, Piedra and Ebrón river valleys were mapped, stratigraphically described chronologically referenced from U/Th disequilibrium series, amino acid racemization radiocarbon methods. Tufa accumulated cascades, barrage-cascades related damming areas developed stepped systems. maximum frequency deposition was identified at 120 ka...
Numerous groundwater analyses from the crystalline bedrock in Forsmark area have been performed between 2002 and 2019, together with thorough geological, geophysical, hydrogeological studies, within site investigations carried out by Swedish Nuclear Fuel Waste Management Company. The samples taken boreholes down to ≈ 1,000 m analysis include major- trace-elements, stable radiogenic isotopes, gases microbes. chemical isotopic composition of these groundwaters evidences presence non-marine...
Abstract This contribution examines the climate variations reflected by a mainly lacustrine succession spanning from 17.73 to 14.0 Ma in north‐east Iberia, thus encompassing Miocene Climatic Optimum (MCO). The study is based on δ 13 C and 18 O composition of an array carbonate facies marl samples, complemented with sedimentological analysis, illite crystallinity index magnetic susceptibility data. onset ending MCO have been detected at ca 17.10‐17.06 14.56 Ma, roughly equivalent boundaries...
Abstract Physical and hydrochemical parameters sedimentation rates were monitored twice a year from August 1999 to March 2003 at the Monasterio de Piedra area (NE Spain). Different tufa facies related distinct fluvial subenvironments characterized isotopic composition of water was analysed seasonally. Sedimentary features (thickness, texture structure) stable isotope seasonal record on tablets analysed. The intervals identified six-monthly thickness measurements tablets. Sedimentation had...
The processes controlling tufa deposition along the River Mesa (NE Spain) were studied from April 2003 to September 2009, based on six-monthly monitoring of physical and chemical parameters river water sedimentological characteristics, including rates tablets. With a mean annual discharge around 1.5m3/s, sedimentation rate (mean 2mm/yr) recorded important spatial, seasonal interannual variations. waters are calcium bicarbonate type. In this study, three distinct stretches distinguished...
The databases SOLTHERM and Yucca Mountain Project (YMP) were converted from GeoT/TOUGHREACT to PHREEQC format, not only allow a higher accessibility of freely available data for thermodynamic modelling in the temperature range 0−350 °C at pressure water vapour saturation, but also show possible causes differences between simulations using two programs. Converted verified by comparing results obtained with same performed GeoT. Four natural geothermal solutions previously published works used...
Abstract A 12-year study (2000–2012) of the stable isotopes recent fluvial tufas has been performed in Monasterio de Piedra Natural Park (River Piedra, NE Iberian Peninsula), an area Mediterranean climate with intense tufa deposition since Pleistocene. The biannual monitoring calcite δ13C and δ18O signatures water value demonstrated a clear seasonal pattern for tufa-calcite oxygen isotope composition, less negative values cool periods, which is consistent regional temperature oscillations....
Elevated U concentrations, most evident in a section ∼500 mbsl, have been measured deep Fe(II)-containing groundwater at Forsmark, eastern Sweden and prompted detailed geochemical isotopic investigations. The highest contents (up to 175 μg/L) are associated with HCO3− of 120-135 mg/L Ca2+ 900-1050 mg/L. Geochemical modelling shows that elevated dissolved can be stabilized by Ca-uranyl-carbonate complexes. Indeed, time resolved luminescence spectrometry confirmed the Ca2UO2(CO3)30 complex,...
