Organic residue analysis of Egyptian votive mummies and their research potential
YesVast numbers of votive mummies were produced in Egypt during the Late Pharaonic, Ptolemaic, and Roman
periods. Although millions remain in situ, many were removed and have ultimately entered museum
collections around the world. There they have often languished as uncomfortable reminders of antiquarian
practices with little information available to enhance their value as artefacts worthy of conservation or
display. A multi-disciplinary research project, based at the University of Manchester, is currently
redressing these issues. One recent aspect of this work has been the characterization of natural products
employed in the mummification of votive bundles. Using gas chromatography–mass spectrometry and the
well-established biomarker approach, analysis of 24 samples from 17 mummy bundles has demonstrated
the presence of oils/fats, natural waxes, petroleum products, resinous exudates, and essential oils. These
results confirm the range of organic materials employed in embalming and augment our understanding of
the treatment of votives. In this first systematic initiative of its kind, initial findings point to possible trends in
body treatment practices in relation to chronology, geography, and changes in ideology which will be
investigated as the study progresses. Detailed knowledge of the substances used on individual bundles
has also served to enhance their value as display items and aid in their conservation.RCB is supported by a PhD studentship from the Art and Humanities Research Council (43019R00209). L.M. and S.A.W. are supported by a Leverhulme Trust Research Project Award (RPG-2013-143)

Géodynamique andine : résumé étendus = Andean geodynamics : extended abstracts
Les roches ignées sodiques sont communes de l'Equateur au sud du Chili. Celles d'âge tertiaire à quaternaire forment les volcans et les plutons au dessus de la croûte andine épaissie au Miocène. Avec les plus vieux plutons paléozoïques, ils sont considérés comme étant formés par fusion d'une croûte inférieure épaisse basaltique, et leur présence indique des périodes d'épaississement crustal.
