Archaeologists have chemically distinguished the vitreous stone of the Rogerson Formation of southern Idaho, northeast Nevada, and northwest Utah as the Browns Bench Toolstone Source. Recent geologic research into the Rogerson Formation reveals that the deposits are much more variable than archaeologists recognize. Multiple potential toolstone beds with unique properties are present within the formation. This material is referred to as ignimbrite by geologists though some of it has the visual...
Geology First, and Geochemistry Last (but Not Last) (2021)
This is an abstract from the "Case Studies in Toolstone Provenance: Reliable Ascription from the Ground Up" session, at the 86th annual meeting of the Society for American Archaeology. In this paper I present my perspective, based on 25 years of fieldwork, on the importance of geologically based approaches to sourcing lithic raw materials. Examples are presented from geoarchaeological fieldwork in Maine, New York, Vermont, New Brunswick, and Quebec. Observing and sampling an outcrop in situ...
Prehistoric Tool Stone Acquisition and Use in the Central Mojave Desert (2018)
Diverse rocks of the Precambrian to the Late Cenozoic are exposed across the greater Mojave Desert Region. In the central Mojave, locations with concentrations of knapable materials are prevalent. Most of these sources are deflated alluvial fan deposits; less than five percent are outcrops. Over the last 13,000 years people have been using the area, percussion biface reduction dominated at both the material extraction sites and habitation and special activity sites. Igneous materials were...
