GAIA creates its own reference material in order to perform scientific laboratory analysis, and deliver fast and effective results.

Three reference collections are available, one of which has been recognized by the archaeology members of the international scientific community.


Lithic Collection

Created by experimental archaeology, this reference collection is essential to use-wear analysis of lithic material.


Seed Collection

Created by aquired organic modern material, wild species, and private donations, this reference collection is essential to archaeological seed analysis.


Wood Charcoal Collection

Created by experimentation and by private and institution donations, this reference collection contains specimen from various countries. This reference collection has recently been integrated to a world wood charcoal reference collections list (Scheel-Ybert, R. 2016. Charcoal collections of the world. International Association of Wood Anatomists Journal 37 (3): 489-505).
