Sources of the Quartzite of Some Ancient Egyptian Sculptures
This article reports the results of analysis of samples collected from some Egyptian quartzite artifacts. such as statuary, dating from the New Kingdom. Most of the artifacts are located in Upper Egypt, but the results of analysis suggest that, until the middle of the fourteenth century B.C., the quartzite came from a more distant quarry near Cairo rather than from the quartzite quarries located near Aswan in Upper Egypt
Correlation of the Rockland Ash Bed, a 400,000-Year-Old Stratigraphic Marker in Northern California and Western Nevada, and Implications for Middle Pleistocene Paleogeography of Central California
Outcrops of an ash bed at several localities in northern California and western Nevada belong to a single air-fall ash layer, the informally named Rockland ash bed, dated at about 400,000 yr B.P. The informal Rockland pumice tuff breccia, a thick, coarse, compound tephra deposit southwest of Lassen Peak in northeastern California, is the near-source equivalent of the Rockland ash bed. Relations between initial thickness of the Rockland ash bed an…
The Northern Colossus of Memnon
Chemical and petrographic studies of the two 720‐ton ‘Colossi of Memnon’ located near Luxor, and of Egyptian quartzite quarries indicate that the rear pedestal blocks of the northern statue were quarried at Aswan, while the other, main components of the monuments were quarried near Cairo. Our studies suggest that the rear pedestal blocks of the northern statue were part of the reconstruction project undertaken by Roman emperor Septimius Severus. …
Mayan Obsidian
High‐precision neutron activation measurements have been made on mesoamerican obsidian from Ixtepeque and El Chayal which are thought to be the major sources of volcanic glass artifacts in pre‐Columbian times. These results are compared with measurements on obsidian artifacts from Lubaantun, Wild Cane Cay, Frenchman's Cay and Moho Cay
Composition Variations in Obsidian Sources and the Archaeological Implications
S An obsidian source can exhibit considerable variations in chemical composition. One such flow at Borax Lake in Lake County, California has been carefully investigated by neutron activation analysis of specimens from a number of different loci. It was found that the variable elements were completely coherent, and thus judgements concerning provenience could be just as definitive as with extremely homogeneous materials
