Sažetak
Recent studies have shown that Esie stone sculptures, the largest collection in Africa, were carved using talc-tremolite, talc-chlorite, talc-tremolite-anthophyllite, and talc- amphibolite schists. However, the light elements were not covered because PIXE is not adequate for elements lighter than silicon. For the first time, PIGE analysis of the sculptures and the outcrops were carried out using protons produced by a 7 MV CN Van de Graaff accelerator at INFN Laboratori Nazionali di Legnaro, Padova, Italy, and a Ge(Li) detector. Talc-schists, the material from which the sculptures were carved, are quite important economically, finding use in the manufacture of paint, ceramics, abrasives, tiles, asbestos, cement and a few other metallurgical applications. Results of these novel measurements are presented.
