investigate their formation and relative chronology. Preliminary results of stratigraphicand micromorphological analyses demonstrate that episodes of hearth use wereinterrupted by periods of disuse and possible site abandonment, and that it laterfunctioned as a pit for domestic waste. These analyses also support a cultural origin forthe hill-like feature and indicate that it precedes the formation of the hearth. Theseinvestigations suggest a broader history of cultural activity at Fort Denison that includesthe periods preceding and post-dating military occupation of the site.Gilliland, Krista (Western Heritage, St Albert), W. Paul Adderley (University ofStirling), Terrance Gibson (Western Heritage, St Albert), Dave Norris (WesternHeritage, Winnipeg) Context, Chronology, and Culture: Problem-basedGeoarchaeology at the Lakehead Complex Sites, Thunder Bay (19) With the goal ofadvancing site interpretations to include the broader landscape and cultural contexts,geoarchaeological work at the Lakehead Complex/Interlake Complex sites in the ThunderBay region is addressing three fundamental problems. Firstly, we comment on the natureand extent of disturbance and redeposition at these sites. Secondly, we investigate theorigin of pit-like depressions that are frequently associated with more deeply buriedartifact-bearing sediments. Thirdly, we address the relative lack of a detailed chronologyfor these sites. Using a combination of stratigraphic and thin section analyses,luminescence profiling, and optical dating, we document the depositional history ofpredominantly artifact-bearing sediments to construct key stratigraphic and chronologicalframeworks for the site complex. Our work has broader resonance with current issuesregarding interpreting archaeological sites in fluvial landscapes, establishing chronologiesat sites with poor organic preservation, and employing sediment-based evidence to furtherunderstandings of sites found in Boreal forest settings.Gillot, Céline (Doctorante, Département d'Anthropologie, Université de Montréal)The role of thin section petrography in the understanding of ancient architecturalpractices: A case study from the Maya site of Río Bec (Mexico)(21) Despite the significantachievements made over the last few decades in the scientific examination ofarchaeological materials and the constant development of new efficient analyticaltechniques, conventional thin section petrography continues to hold an important place inthe archaeologist's toolkit. Simple observation of thin sections with a polarizingmicroscope still has the potential to provide large amount of information not easilyobtained by other methods. In some cases, this basic method can even be sufficient toanswer the archaeologists' questions. Using as an example the work carried out on thebuilding materials employed in the prehispanic Maya site of Río Bec, this presentationaims to demonstrate how valuable petrographic analyses are for the understanding of pastarchitectures in particular. They may bring new insights not only on the building materialsand the construction techniques, but also on the technological choices made by thebuilders and the reasons behind these choices.Girard-Rheault, Marilyn, (Université de Montréal) Les camélidés et l’archéologiepéruvienne (1) Les camélidés furent les mammifères les plus polyvalents pour l’hommeen Amérique du sud avant l’arrivée des colons.
