Étude de collections de paléontologie

Abstract

Paleontology Collections include many fossils containing sulphides, such as pyrite which is a widespread iron sulphide. When exposed to the open air, these sulphides are prone to oxidation and give rise to remarkable efflorescence that hide the fossil print and weaken the matrices. This work aims reproduce these damages in laboratory conditions in order to study them.
