“…Raman and FT-IR spectroscopies 5,6 , X ray microCT [7][8][9] , NanoSIMs 10 ) to the study of fossils has expanded research in paleobiology and led it to a higher level of sophistication, and it is called paleometry 11 . Inspired in the well established Brazilian archaeometry which studies archaeological, etnographical and the so called patrimonial materials [12][13][14][15][16] , the application of paleometrical techniques to the study of many Brazilian fossils is still growing [17][18][19][20][21] and opening new perspectives to deepen our knowledge of the biological affinities and paleoecological aspects. Some exceptionally well-preserved fossils (e.g.…”

Paleometry is a promising research field that brings together different areas, such as physics and chemistry, applied to paleobiological issues. In spite of being recognized abroad, it is a new research field in Brazil. The most important characteristic is the application of mostly non-destructive techniques to the study of fossils. This work compiles some paleometrical applications to different geological contexts, such as the synthesis of hard skeleton in Corumbella werneri, geochemical aspects about fresh water bivalves from the Bauru Group and the exceptional preservation of arthropods from the Crato Member. Diffuse Reflectance Infrared (DRIFT) and Energy Dispersive X-ray Spectroscopy (EDX) were complementary to elucidate the types of skeletogenesys in Corumbella. In the case of the bivalves, DRIFT revealed to be important to elucidate aspects about death and fossilization. Among arthropods, morphological analysis with Scanning Electron Microscopy (SEM) associated with EDX was more profitable to understand fossilization process and paleoenvironmental implications.

“…The physical and chemical characterization of archaeological ceramics is useful, because it may provide information on the external and internal structures of the fragments (heterogeneity, seasoning and porosity), which help to indicate the origin of the samples (Lima et al . 2011). In addition, the physical and chemical characterization of ceramics provides data that may reveal many aspects about the manufacturing processes, the degree of technological development of the culture that made it, the origin of the raw materials, and the commercial exchange networks used among the nations and peoples of the world's ancestral cultures (Homem 2006).…”

Gamma‐ray spectrometry in the characterization of diverse‐geometry archaeological ceramics

et al. 2020

This study contributes to the insertion of the gamma‐ray spectrometry technique in archaeometry by presenting spectral analysis methods to determine the ratios between the absolute concentrations of the radioelements eTh (ppm), eU (ppm) and K (%) in archaeological ceramics without strict control of geometry. The absolute ratio results for samples of diverse geometry are consistent with the results obtained for samples with geometric control at a 95% level of statistical significance. In order to show a real archaeometry case, the methods were applied in the analysis of 14 ceramic pieces of three archaeological sites of Maranhão state (Brazil).

Investigative analyses of metallic objects from the tomb of a queen of the Moche civilization, who lived around 100 to 300 AD in the northern coast of current Peru, known as Lady of Cao, have been carried out by researchers in the last 4 years using various destructive techniques. Many of these objects found inside the tomb are jewelry produced using silver, gilded copper, copper, and gold sheets. The application of X‐ray microtomography (μCT) and X‐ray digital radiography techniques using a portable system had the objective of obtaining more information on the structures of the objects studied, and thus to obtain some evidences about the production methods used by Moche artisans. In this way, radiographic and microtomographic images were acquired, and qualitative and quantitative analyses were performed. A fish in gold and a nose decoration in silver were examined by radiographic methods, whereas a silver earring and a gold needle were analyzed by μCT. Important information on the structure of these objects were gained.
