Thermal modelling of orogenic mesothermal deposits : application to Ghana

open access: green, 2005
Cette thèse vise à comprendre les processus thermiques et les régimes d'écoulement de fluides menant à la genèse de gisements d'or mésothermaux. Deux approches de modélisation numérique sont utilisées, une régionale, caractérisant le régime thermique conductif pré-minéralisation et l'autre locale ajoutant la convection hydrothermale syn-minéralisation.
