Origine des pegmatites du Cap de Creus : approche intégrée de terrain, pétrologie et géochimie

Abstract : Since several decades, the debate on the origin of pegmatite formation has led to the development of two models, a granitic model and an anatectic model. Although these models are commonly accepted by the scientific community, they rely mainly on geochemical and/or petrological criteria, occasionally on geochronological datas, and rarely on structural criteria. The aim of my thesis is to study and to determine the origin -granitic vs anatectic- of the Cap de Creus pegmatites (Spain) by combining structural and geochemical studies. In-situ analyses (microprobe, LA-ICPMS) combined with different structural works and microstructural observations, both in pegmatites and their host rock, allowed me to establish a relative chronology of pegmatite emplacement, but also to replace the origin of the Cap de Creus pegmatites in a regional geodynamic model, thus highlighting two pegmatite fields of different origins.
