Since the 1960s, x-ray fluorescence spectrometry (XRF), both wavelength and energy-dispersive have served as the workhorse for non-destructive and destructive analyses of archaeological materials. Recently eclipsed by other instrumentation such as LA-ICP-MS, XRF remains the mainstay of non-destructive chemical analyses in archaeology, particularly for volcanic rocks, and most particularly for obsidian. In a world where heritage and repatriation issues drive archaeological method and theory, XRF remains an important tool for understanding the human past, and will remain so for decades to come. Currently, there is no comprehensive book in XRF applications in archaeology at a time when the applications of portable XRF and desktop XRF instrumentation are exploding particularly in anthropology and archaeology departments worldwide. The contributors to this volume are the experts in the field, and most are at the forefront of the newest applications of XRF to archaeological problems. It covers all relevant aspects of the field for those using the newest XRF technologies to deal with very current issues in archaeology.

The American Southwest is the focus for this volume in Noel Justice's series of reference works that survey, describe, and categorize the projectile point and cutting tools used in prehistory by Native American peoples. Written for archaeologists and amateur collectors alike, the book describes over 50 types of stone arrowhead and spear points according to period, culture, and region. With the knowledge of someone trained to fashion projectile points with techniques used by the Indians, Justice describes how the points were made, used, and re-sharpened. His detailed drawings illustrate the way the Indians shaped their tools, what styles were peculiar to which regions, and how the various types can best be identified. There are hundreds of drawings, organized by type cluster and other identifying characteristics. The book also includes distribution maps and color plates that will further aid the researcher or collector in identifying specific periods, cultures, and projectile types.

Noel Justice adds another regional guide to his series of important reference works that survey, describe, and categorize the projectile point and cutting tools used in prehistory by Native American peoples.
