Particular features of the application of IR reflection spectroscopy methods in studies in archeology and paleontology

Functional characterization of Mousterian tools from the Caucasus using comprehensive use-wear and residue analysis

“…9 , 49 , 77 – 81 ] established the methodological framework for examination of archaeological residues in our study. The absorption bands corresponding to specific bitumen bands were defined after 32 – 34 , 73 – 75 . Band assignments for Raman peaks were made based on 36 .…”

Investigation of Mammoth Tusks from the Paleolithic Sites of the European Part of Russia by the IR Reflection Spectroscopy

“…In [1], an optical model of the rough surface of a real object typical of archeology and paleontology [2,3] was considered. To implement this model, data on the optical properties of the object in the IR spectral region are needed.…”

“…Since the basis of objects (fragments of mammoth tusks) of paleontology includes the mineral apatite Ca 5 (PO 4 ) 3 (OH), its spectral absorption characteristics were determined in the range of 6-28 microns [4]. This made it possible to correctly process the IR spectra of the specular reflection of several objects (fragments of mammoth tusks) [1]. In [5] a comparison was made of the sensitivity of nondestructive methods of specular and diffuse reflection.…”

“…The results are compared with traditional methods of diffuse infrared reflection and the KBr technique. [1] were obtained from the holdings of the Museum of Anthropology and Ethnography of the Russian Academy of Sciences. The specimens were predominantly slivers split off from mammoth tusks used in household activities of ancient people and artifacts (Figure 1) decorated with carved rhombic ornaments, which were found upon excavation at two paleolithic sites that are situated in Yudinovo (Bryansk oblast, Russia).…”
