L’un de ces systèmes, le QEMSCAN a été acquis par l’Université de Genève, avec l’aide financière du FNS est le seul en Suisse et la troisième machine en Europe de ce genre. Cela donne à la communauté scientifique suisse un atout excellence et d’unicité.
Lay summary

Contenu et objectifs du travail de recherche

Notre principal objectif est de contribuer à une meilleure compréhension de la variabilité de composition des roches qui forment notre Planète. En particulier, le QEMSCAN sera appliqué en grande partie pour l'analyse des bassins sédimentaires. L’analyse contribuera à la compréhension des propriétés des roches dans la perspective d’identifier et d’évaluer les ressources naturelles (eau, hydrocarbures, géothermie, minerais, etc.) ou l’entreposage de matériel (déchets nucléaires, CO2).

Plusieurs autres projets, telles l’étude de poussières volcaniques et les risques associés, l’étude des effets des polluants sur le sols, la nature et provenance des céramiques préhistoriques, des applications dans les études médico-légales, l’analyse des matériaux de construction etc., seront aussi développés grâce à cette nouvelle technologie.

Contexte scientifique et social du projet de recherche

Notre recherche générera des informations inédites et essentielles sur plusieurs fronts. Les résultats permettront de conseiller le monde de la recherche, l’industrie et aussi le monde politique en fournissant des éléments nouveaux pour la connaissance de notre Planète et les enjeux associés (exploitation des ressources naturelles, pollutions, etc.).

Abstract

The Section of Earth and Environmental Sciences of the University of Geneva (UNIGE) plans to acquire a QEMSCAN. QEMSCAN is an automated technique for the rapid characterization of mineral species and relationships by scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS). Af-ter its development primarily for the mining industry, QEMSCAN has been ap-plied for basin analysis research by the hydrocarbon industry. In most recent years QUMSCAN has gained recognition in numerous other scientific domains. Because of its analysis rapidity, QEMSCAN technology is able to resolve de-tailed mineralogical compositions at a much larger scale than with any other existing methods.Recent developments show that QEMSCAN is a technique that open new re-search fields and several Universities and other research institutions in Aus-tralia -where it was developed-, Europe and North America have acquired or are acquiring it. The QEMSCAN for which we are requesting partial funding will be the first in Switzerland and will create a large number of innovative research directions in several disciplines. The main advantage of QEMSCAM is the ability to acquire rapid quantitative data on mineral composition, lithotypes, grain size and shape (angularity), grain and bulk density and porosity from the same sample. The main applicant will mainly use the QEMSCAN technology to study heterogeneous sedimentary facies associated with glaciogenic and alluvial reservoirs in order to develop sound predictive genetic models. Clastic sediment characterization and quanti-fication in a high-resolution mode is often neglected since it is very time con-suming, and, yet, is critical for correct interpretation. The use of QEMSCAN methodology provides an ideal solution to this problem allowing a fast and de-tailed sediment typing. This is essential because it allows to treat a sufficient number of samples for realistic 3D reconstructions of the depositional envi-ronment. The Ore Deposits Group at the University of Geneva will also make wide use of the equipment (characterization of alteration assemblages and of their textural relationships, zoning of alteration and ore minerals at different scales, localization of trace minerals). The proposal lists numerous other pro-jects ranging from geochronology (to localization of datable trace minerals), en-vironmental sciences, sedimentology and sedimentary petrography, reservoir geology, source-to-sink basin studies, micropaleontology, limnology and lim-nogeology, mineralogy, petrology, hydrogeology, volcanology, archaeology and forensic sciences.In summary, access to automated, high-resolution technology capable to ana-lyse rapidly and in a highly accurate way hundreds to several hundreds of samples at micrometric scale, represents a new opportunity for natural and physical sciences which will open new quantitative ways of conducting scien-tific investigations, which were not realistically feasible in the past. The Section of Earth and Environmental sciences will attribute a position for technical staff responsible for the use and maintenance of this new equipment. This instrument will complement the large analytical equipment existing at the Universities of Geneva and Lausanne and will be accessible to the other scien-tists from the Lemanic region and the rest of Switzerland.
