Análise tecno-funcional do material lítico das camadas 1 a 3 – setor d-2: sítio cachoeira do pingador, mt

Abstract

In the present work, an analysis was carried out of the lithic material of the three upper layers of sector D-2 of the Cachoeira do Pingador site, Manso river valley/MT. This sector is located at the bottom of a shelter 22 m long and 1.0-8.5 m deep. The studied interval comprises levels between 0-100 cm deep and has dates ranging from 1,000+-60 BP to 1,620+-60 BP, in layers two and three. The site had lithic, ceramic, bone material (from small vertebrates), malacofauna and vegetables exhumed, collected and researched due to the “Projeto de Levantamento e Resgate do Patrimônio Arqueológico Pré-Histórico da Região da Usina Hidrelétrica de Manso/MT”, under the coordination of professor Sibeli Aparecida Viana, and the material is managed by PUC Goiás/IGPA. The lithic analyzes were based on the techno-functional approach, and the notion of an operative chain, with the aim of identifying the different techniques used and the functional potentials related to the lithic tools (edges and prehensile areas). The tools analyzed have low visibility, with the most frequent technical principle being type “C” Debitage, but there were also tools in flakes obtained by Modeling and Kombewa support flakes, coming from type “D” Debitage, which approximates the material from the one part of the set studied before. The occurrence of a core explored by pyramidal Debitage D also corroborates this perspective. The presence of Afordance lato sensu was found in almost all seven technotypes identified for sector D-2 and is one of the characteristics that distinguishes the sector studied in relation to another sector (H-0) previously studied, located at the entrance to the shelter, which shows the Afordance stricto sensu in all technotypes
