Description

This article is the first in the Alberta Lithic Reference Project series, the goal of which is to assist the identification of raw materials used for pre-contact stone tools in the province. Each article will focus on one raw material; the current article discusses a partially fused, glassy, vesicular rock that originates in Northwest Territories called Tertiary Hills Clinker (THC). THC appears in archaeological sites in northern and central Alberta. A suite of techniques indicates that it can be geochemically sourced much like obsidian. The accurate identification of THC can reveal significant relationships between occupants of Alberta and the Mackenzie Basin to the north.

Description

This article is the second in the Alberta Lithic Reference Project series, the goal of which is to assist the identification of raw materials used for pre-contact stone tools in the province. Each article focuses on one raw material; the current article discusses a microcrystalline, actinolite-tremolite (amphibole)-rich rock called nephrite (jade) that originates in British Columbia, Washington, Yukon, and Alaska. Nephrite appears in archaeological sites in northern and central Alberta. This articles presents results from a variety of non-destructive techniques to determine the geochemistry and mineralogy of nephrite ground stone celts found in Alberta. The accurate identification of nephrite can reveal significant cultural relationships that involved long distance exchange of raw materials between occupants of Alberta and British Columbia.

Description

This article is the third in the Alberta Lithic Reference Project series, the goal of which is to assist the identification of raw materials used for pre-contact stone tools in the province. Each article focuses on one raw material; the current article discusses a silicified orthoquartzite sedimentary rock that originates in northeast Alberta called Beaver River Sandstone (BRS). BRS appears in archaeological sites in northern and central Alberta. This paper offers a description of BRS and comparable Montana materials, a photographic library for comparative purposes, a brief summary of BRS utilization in northeast Alberta, and data to facilitate the accurate identification of BRS in archaeological assemblages.
