Micro-attenuated total reflection spectral imaging in archaeology: application to Maya paint and plaster wall decorations
Goodall, Rosemary A., Hall, Jay, Sharer, Robert, Traxler, Loa, Rintoul, Llew, & Fredericks, Peter M. (2008) Micro-attenuated total reflection spectral imaging in archaeology: application to Maya paint and plaster wall decorations. Applied Spectroscopy, 62(1), pp. 10-16.
Fourier transform infrared - attenuated total reflection imaging has been successfully used to identify individual mineral components of ancient Maya paint. The high spatial resolution of a micro FT-IR-ATR system in combination with a focal plane array detector has meant that individual particles in the paint have been resolved and identified from their spectra. This system has been used in combination with micro-Raman spectroscopy to characterize the paint which was found to be a mixture of hematite and silicate particles with minor amounts of calcite, carbon and magnetite particles in a sub-micron hematite and calcite matrix. The underlying stucco was also investigated and found to be a combination of calcite with fine carbon particles, making a dark sub-ground for the paint.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
