TITLE:

ARCHEOMETRIC INVESTIGATION OF BLACK EARTH SOIL FROM SITE BITOCA (Amazon Region, PARÁ)

SUMMARY:

The present study investigated by bibliographic summary, several researches that used some chemical analysis methodology to observe the patterns of soils and ceramics in the region. From then on, it started to observe 16 archaeological soil samples from Bitoca I and II sites, located in the Salobo area (Pará). SEM and total chemical and fertility/nutrient analysis to determine CTC, SB, pH, among other factors. Mineralogical characterization points to similarity between sites I and II, and they presented mostly a common mineralogy composed of kaolinite and quartz, showing the correlation with the mineralogy of Amazonian soils, as well as the pH revealed an average of 5.26 for H2O and 5.16 for KCl (I mol.LI) and are in agreement with the mean of the pH values observed for the TPI found in the Amazon. It stands out among the values obtained from the pile hole sediment samples (E1S8-6 and E5T1S-5) that presented high levels for SB (54.42 and 37.27 cmolc/Kg) and CTC (63.92 and 47.97 cmolc/ Kg). Other evidence is the presence of calcite pointing to evidence of shells or molluscs and cristobalite suggesting the calcination of amorphous silica, a phase normally found in plants in the region, such as cariapé and kauixi. Chemical characterizations show that the E4S7-1 sample (hut structures) has the highest contents of Ca (10460 ppm) and P (1700 ppm), evidencing the disposal of animal and vegetable food residues, among other daily activities. The bonfire samples (E3SO-1A4, E7T1SE-7, E7T1SE-6 and E6T1N5) also have high levels of Ca and P, allowing the assumption of using these bonfires for cooking food (possibly of animal origin). The soils of the Bitoca I site have a mineralogical composition similar to those of the Bitoca II site, especially quartz and kaolinite, while the calcite, muscovite, anatase, hematite, goethite and gibbsite phases were observed in smaller amounts.
