Distribution and sources of obsidian in the Rio Grande gravels of New Mexico
The obsidian in the gravels deposited by the Rio Grande in New Mexico has interested archaeologists of the region, particularly the use of these gravels by prehistoric populations and the implications for obsidian sourcing studies. Previous investigations of Rio Grande gravel obsidian have focused on obsidian in the archaeological record. This study focuses on the natural occurrence and distribution of obsidian in the gravels and the implications…
The Magnetic Susceptibility of Southwestern Obsidian
The magnetic properties of volcanic glass and obsidian have long been known. Selected magnetic properties have proven useful discriminators among eastern Mediterranean obsidian sources. A recent exploratory study of the magnetic susceptibility of Southwestern obsidians indicates that it may prove a useful tool in this region also. Magnetic measurements of samples from many of the major obsidian sources in the Southwest were analyzed in an explora…
Lithic Resources of the Bearlodge Mountains, Wyoming
The Bearlodge Mountains of northeast Wyoming contain substantial outcrops of stone that were extensively exploited by prehistoric people. Among these are orthoquartzites from the Lakota and Fall River formations, as well as chalcedonies (including a KRF look-alike) and orthoquartzites from the Morrison formation. The data presented result from a materials-centered study of the lithic resources of the Black Hills National Forest. A predictive mode…
Comment on “neutron activation analysis of stone from theChadron formation and a Clovis Site on the Great Plains” by Hoard et al. (1992)
Ogalalla Orthoquartzite
Ogallala orthoquartzite (commonly called Bijou Hills silicified sediment or quartzite) is a common material found at some sites in South Dakota along the Missouri River and extending into Nebraska. This paper provides a fuller geologic description of the rock than previously available. It also discusses the procurement method at two sites, 39TP6 and 39TP7, in Tripp County, South Dakota
