Abstract
Five fired-brick sites, tentatively attributed to the Kanem-Borno State, were test-excavated, and samples of fired bricks and wood charcoal were dated using optically stimulated luminescence (OSL) and accelerator mass spectrometry (AMS). Although OSL yielded larger standard deviations compared to radiocarbon dating, both methods produced chronologically significant results. In addition to confirming that the sites were constructed during Kanem-Borno’s rule over Kanem, the new dates support earlier suggestions of multi-phase construction of similar nearby locations. To systematically analyze the growing body of chronometric data from Kanem, we employed Bayesian chronological modelling. This method not only identifies potential stratigraphic and chronological outliers but also provides probabilistic evidence for the multi-phase development of these sites.
期刊介绍：
African Archaeological Review publishes original research articles, review essays, reports, book/media reviews, and forums/commentaries on African archaeology, highlighting the contributions of the African continent to critical global issues in the past and present. Relevant topics include the emergence of modern humans and earliest manifestations of human culture; subsistence, agricultural, and technological innovations; and social complexity, as well as topical issues on heritage. The journal features timely continental and subcontinental studies covering cultural and historical processes; interregional interactions; biocultural evolution; cultural dynamics and ecology; the role of cultural materials in politics, ideology, and religion; different dimensions of economic life; the application of historical, textual, ethnoarchaeological, and archaeometric data in archaeological interpretation; and the intersections of cultural heritage, information technology, and community/public archaeology.
