A presente pesquisa constitui uma investigação geoarqueológica sobre a Lagoa Uri de Cima, localizada no município de Salgueiro-PE, abordando três escalas de análise: a escala macro, representada pelo ambiente da Lagoa, a escala meso, pela sequência estratigráfica dos sedimentos que preencheram a Lagoa, com cronologias LOE de 34.600 ± 690 anos AP até 3.50 ±3 60 anos AP e a escala micro formada especificamente pelos dois níveis mais profundos da Lagoa, o de cascalheira cimentada por concreção carbonática, que constitui um calcrete e, pelo nível arenoso sobreposto a cascalheira.
GEOARCHAEOLOGICAL STUDY OF THE SANDY LAYER AND THE CEMENTED BY CARBONATE CONCRETION GRAVEL LAYER, FROM THE SITE LAGOA URI DE CIMA, SALGUEIRO, PE
ABSTRACT
This research is a geoarchaeological study about Lagoa Uri de Cima, situated in Salgueiro county, state of Pernambuco. The methodological approach was built through three scales of analysis: the macro scale, represented by the lagoon environment, the meso scale composed by the stratigraphy sequence of the sediments that filled the pond, with ages from 34,600 ± 690 years BP until 3500 ± 360 years BP and, the micro scale formed specifically by the two deepest layers of the lagoon, the gravel layer cemented by carbonate concretion, which formed a calcrete and the sandy layer deposited above the gravel.
Keywords: Geoarchaeology; lagoon; calcrete.
