Quantitative analysis of micromorphological images in edaphosedimentary sequences of the archaeological sites of Tequendama and Aguazuque, Sabana de Bogotá, Colombia

Abstract

The Bogotá savanna is a very important site for Colombian archeology. At this site, researchers have identified the settlements of hunter-gatherers and agricultural farmers who inhabited the territory from the late Pleistocene to the late Holocene. These archaeological studies have established the ways of life, social dynamics and environmental interactions of these groups. To clarify settlement processes, this article presents a detailed micromorphological and micromorphometric analysis of sediments collected in archeological excavations conducted at the Tequendama and Aguazuque sites in the municipality of Soacha, Cundinamarca. This analysis quantifies the contents of archaeological materials, such as bone and coal, as well as carbonate remains, which are associated with various activities. The results show differences in the abundance of bones and charcoal between settlement levels. Level 7A (dated 6,897-7,001 BP) of the Tequendama site shows the highest density of occupation and activities of all levels analyzed in this study. Furthermore, based on paleoenvironmental interpretation, the presence of secondary carbonates indicates arid conditions in the Bogotá savanna matching the regional climatic records.
