Preliminary analysis of Palaeolithic black pigments in plaquettes from the Parpalló cave (Gandía, Spain) carried out by means of non-destructive techniques
Abstract Parpallo cave (Gandia, Spain) is one of the most important Palaeolithic sites in the Spanish Mediterranean region. It is characterized by a mobiliary art whose archaeological sequence covers a dilated period (26,000–11,000 BP) and includes plaquettes decorated with black and different shades of red and yellow pigments. The aim of this paper is to present the results of analyses of the nature of black pigments used in the decoration of Parpallo plaquettes. The analyses were carried out by a non-destructive technique, by means of EDXRF. Furthermore, a colorimetric data bank has been created for conservation purposes. EDXRF measurements directly identify the use of manganese black pig…
Archaeometric study of ceramic figurines from the Maya settlement of La Blanca (Petén, Guatemala)
Abstract In this article, analytical results will be presented and discussed regarding a selected set of figurines from the ancient Maya settlement of La Blanca in Peten, Guatemala. The objective is to characterize the ceramic material by two analytical complementary techniques: X-ray diffraction (XRD) and total reflection X-ray fluorescence (TXRF). The data obtained by means of both XRD and TXRF were compared and analyzed by multivariate statistical techniques in order to obtain sample groups according to their chemical composition. The results of this archaeometric study have been compared to those that have been obtained through macroscopic characterization by means of the traditional cl…
