Ci-dessous, vous trouvez un sujet de thèse financée par l'Andra (Agence nationale pour la gestion des déchets radioactifs).
http://www.andra.fr/pages/fr/menu1/l-andra/nous-rejoindre/allocations-de-theses-de-doctorat-55.html
Pour faire une demande de financement, il faut déposer un dossier avant le 31 Mars auprès de la commission scientifique de l'Andra présentant les caractéristiques suivantes:
1) un sujet répondant à l'appel d'offre thématique (voir ci dessous)
2) un candidat associé au sujet ayant moins de 25 ans.
Description et compréhension de la régulation des réactions d’oxydo-réduction dans les environnements de subsurface
Le but du sujet est de comprendre le contrôle des réactions redox dans un environnement de subsurface, de définir les réactions d'oxydo-réduction dominantes et de décrire les couples redox actifs ainsi que leur cinétique réactionnelle au cours du temps. Dans une approche théorique, un seul couple redox devrait définir le potentiel d'oxydo-réduction du système à l'équilibre. Toutefois, dans les sols et sédiments, de nombreux couples redox coexistent en non-équilibre (phénomène transitoire). Pour mener à bien ce travail de recherche, les approches développées seront à la fois naturalistes, au travers de l’interprétation de données de terrain (analogues naturels en milieu argileux), mais également expérimentales sur des systèmes géochimiques, en réacteurs et en colonnes, bien définis et contraints (toxique chimique au contact d’échantillon argileux). Le sujet s’intéresse particulièrement à caractériser, décrire et comprendre le comportement et la mobilité, dans des conditions oxiques et anoxiques, d’éléments chimiques sensibles au redox et d’intérêt pour l’Andra notamment dans le cadre de la gestion des déchets FAVL (Cr, As, Hg, U...).

The Institute of Geology at the University of Bern, Switzerland, invites applications for a PhD-project on:
“40K-40Ca, 40K-40Ar and 87Rb-87Sr decay constant intercalibration and the 40K branching ratio”
The position is funded by the Swiss National Science Foundation. The objective of the project is to obtain a high precision decay constant for the decay of 40K and the associated branching ratio. The study will involve the comparison of K-Ar and K-Ca ages of well characterized samples with age information from the same material that has been dated with other decay schemes. The project will include the use of thermal ionization, multicollector-ICP and noble gas mass spectrometers.

Phd position in Isotope Geochemistry / Geochronology (1) |
2010 10 30
|
The Institute of Geology at the University of Bern, Switzerland, invites applications for a PhD-project on:
“Rutile as a chronometer for the quantification of orogenic processes”
The position is funded by the Swiss National Science Foundation. The major objective of the project is to investigate the accessory phases, particularly rutile, in high grade metamorphic rocks as potential tracers of geologic processes.
The study will involve trace element and isotope analyses of metamorphic rutiles from granulite facies rocks thermal ionization and (Laser) multicollector-ICP mass spectrometry, as well as microprobe analyses.
Major and trace element analyses combined with radiogenic isotope systems will be used to characterize the behavior of mostly rutile in rocks of different composition during high temperature metamorphism.

PhD position in Geochemistry and Petrology of Silicate Glasses and Melts |
2010 10 25
|
The chemistry and physical state of glassy volcanic phases hold important clues about e.g. distinct phases and styles of magmatic activity, chemical partitioning, magma source conditions and the thermal history of a rock. This project will utilize a multidisciplinary approach in studying volcanic and experimental glasses, to unravel magma genesis and evolution in respect to underlying geological and tectonic processes. The project will rely on a detailed characterization of glasses at a microscopic level using modern analytical methods, such as Raman spectroscopy, ion- and microprobe chemical analysis, FTIR, optical- and scanning electron microscopy, as well as synchrotron radiation based techniques. The acquired knowledge on physical and chemical properties will be translated into the description of generic magmatic processes, as well as their causes and dynamics, by employing quantitative geochemical and petrological modelling tools.
Research directions within the program include traditional and experimental petrology, high-temperature geochemistry, mineralogy, diagenetic processes, tectonic modelling and structural geology. Apart from standard equipment, an electron microprobe, as well as hydrothermal and high-pressure experimental laboratories (autoclave and diamond anvil cell), a tectonic analogue laboratory and an SEM exist amongst the facilities (see http://www.geo.uu.se/mpt).
The candidate should have a background in geosciences or natural sciences. Special attention will be given to candidates with experience in geochemistry, igneous petrology and in-situ mineral analysis using micro-analytical techniques.

PhD Position in Isotope Geochemistry |
2009 12 31
|
We are inviting applications for a three-year doctoral fellowship (Ph.D.) starting in early 2010 in the Isotope Geochemistry Group (Prof. B. Bourdon) at ETH Zurich. This project investigates the origin and processes leading to the current state of compositional heterogeneity in the Earth’s mantle. Combined lithophile isotope analyses on a large range of mantlederived rocks, ranging from some of the oldest rocks on Earth to zeroage oceanic basalts and peridotites will investigate the early differentiation, the secular evolution and current composition of the Earth’s mantle. The project will include method refinement and radiogenic isotope measurements with thermal and plasma ionization mass spectrometry. The successful candidate will be expected to conduct his/her own research in investigating radiogenic isotopes as a tracer for crust-mantle differentiation. Background / Requirements: A completed MSc or Diploma degree in Earth Sciences, preferably with a focus on geochemistry is required. A background in isotope geochemistry, including prior experience in working in clean-room and mass spectrometry facilities is strongly desired. Please send your application (PDF), including cover letter, CV, copies of degree certificates, and the name and contact details of at least two referees by e-mail to: Dr. A. Stracke (stracke@erdw.ethz.ch).
