Mycenaean IIIA and IIIB pottery found in the beehive-shaped Tomb 387 at Laish/Dan and in the rectangular tombs at Akko, in northern Canaan, were subjected to instrumental neutron activation analysis (INAA) to learn where they were manufactured. We we

Obsidian from known outcrops in the Mesoamerican highlands has been recovered from lowland Maya sites, providing significant evidence for long-distance procurement and local redistribution of obsidian by the ancient Maya. Prior chemical-characterizat

We have examined the role of long-distance trade in Prehispanic Ecuador using X-ray fluorescence (XRF) and neutron-activation analysis (NAA) of obsidian artifacts from the archaeological sites of El Inga, Chobshi Cave and Site OGSE-46 on the Santa El

A study by neutron activation analysis and X-ray fluorescence measurements of 116 Ecuadorian obsidian artifacts as well as primary and secondary source samples has shown that the material originated from two Andean sources in north-central Ecuador, a

Philistine bichrome ware from Tell en-Nasbeh, an Israelite village in the hill country, has been characterized by instrumental neutron activation analysis. A group of pottery stylistically indistinguishable from wares made in Philistia is shown to be

Obsidian sources, and the proportions of those sources represented in site collections, are known poorly in the southeast mesoamerican periphery. The Honduran sources of La Esperanza and Güinope are described and “fingerprinted” chemically, and

Iridium anomalies of Late Eocene age are here reported in sequences from northern Italy and Weddell Sea, Antarctic. We have analyzed 270 samples of marly limestones from the Eocene/Oligocene boundary stratotype section at Massignano, Italy, ranging f

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 measurem

Neutron activation measurements for Eu, Sc, Cs. Th, Ta, and Fe on 6 samples of pottery and rock by the Hebrew University and the Lawrence Berkeley Laboratory have been compared. The average disagreement exclusive of counting errors was 1.1%. The prac
