Isotopic composition of bare soil evaporated water vapor. Part II: Modeling of RUBIC IV experimental results
Stable water isotopes such as oxygen 18, are tracers of water movement within the soil vegetation atmosphere system. They provide useful information for a better understanding of evaporation and water vapor transport within soils. In part I of this paper, we presented a novel control experimental set up under non steady conditions, dedicated to the...
Quantification of the partition between bare soil evaporation and plant transpiration using stable water isotopes
Evapotranspiration from continental surfaces is one of the most important components of the global water cycle, but it is certainly the less known. The lack of knowledge is even larger when referring to the partition of evapotranspiration between its components: bare soil evaporation and plant transpiration. Isotopic biogeochemistry can provide use...

Isotopic composition of bare soil evaporated water vapor. Part I: RUBIC IV experimental set up and results
Stable water isotopes such as oxygen 18, are natural tracers of water movement within the soilvegetationatmosphere continuum. They provide useful information for a better understanding of evaporation and water vapor transport within soils. This paper presents a novel controlled experimental set up. It is dedicated to detailed measurements of the ev...
Testing an integrated chronology: I-Xe analysis of enstatite meteorites and a eucrite
We have determined initial I-129/I-121 ratios for mineral concentrates of four enstatite meteorites and a eucrite. In the case of the enstatite meteorites the inferred ages are associated with the pyroxene-rich separates giving pyroxene closure ages relative to the Shallowater standard of Indarch (EH4, 0.04 +/- 0.67 Ma), Khairpur (EL6, -4.22 +/- 0....

Etude géochimique et hydrodynamique de la nappe libre du bassin du lac Tchad dans les régions de Diffa (Niger oriental) ...
La zone d'étude correspond à la nappe libre de l'aquifère quaternaire du BLT au sud-est du Niger (le Kadzell) et au nord-est du Nigeria (Etat du Bornou) où se démarquent deux dépressions piézométriques majeures. L'objectif de ce travail est de contribuer, par une double approche géochimique (ions majeurs et traces, 18O, 2H) et hydrodynamique, à l'i...
Some applications of geochemical and isotopic techniques to hydrogeology of the caves after research in two sites (Nerja...
Caves constitute privileged sampling spots to investigate the hydrochemical behaviour of infiltration, but the representative nature of samples can limit their reach. Taking this into account many results can be obtained from chemistry of water sampled in the caves. Carbonate tracers enable to reconstruct the 'history' of drip water water, includin...
