Abstract
We analysed by PIXE the chemical composition of 50 obsidian artefacts from Colombian and Ecuadorian archaeological coastal sites of the preh ispanic period, and 21 samples from natural outcrops and dated 16 of t hese samples by the fission track method. Geochemical/age characteriza tion of obsidian artefacts show they come from five sources, of which three are unknown. The combination of PIXE and fission track dating ca n refine the grouping of samples into homogeneous clans for sourcing s tudies.
