This is the first review volume devoted solely to the contributions of petrology (i.e., the study of the origin, occurrence, structure, and history of rocks) to archaeology. (Abstractor's note: Most of the 11 contributions are unconcerned with the artistic or practical uses of artifacts or with the history of man's use of stone. ) Papers review and explain techniques of analysis for archaeological artifacts, specifically those made of mineral or stone: techniques of identification, analysis, and dating of stone; classifications of rocks; the petrology of stones used for building and sculpture; Celtic vitrified forts; stone axes and tools; obsidian artifacts; jade axes; sharpening stones, touchstones, and milling stones; ceramics; and of native metals and minerals such as turquoise.
