With 30 years of experience in the field of phytolith analysis, I studied material coming from Europe, the Near East, Central Africa and Easter Island.
Last 20 years and in collaboration with Y. Devos, within the framework of the palaeo- and archaeoenvironmental studies in the Brussels region, we developed the phytolith analysis of archaeological soil thin section. This technique allows to discriminate the depositional histories of the phytoliths as well as to identify those phytoliths sharing a common botanical origin. It also broadens the perspectives for morphometrical analysis of archaeological phytoliths
