For many years the Rosetta Stone was said to have been made from basalt, a fine-grained igneous rock. Recent cleaning and conservation work provided the opportunity to investigate the nature of the stone, its geological classification and its possible geological source. Petrographic observations, coupled with examination and elemental analysis in a scanning electron microscope, have shown that the stone is not basalt, differing both in mineralogy and chemical composition. Rather, it is a… Expand
