AbstractThe methods and techniques presented provide a means for evaluating raw material characteristics in those situations where secondary deposits of lithic materials were exploited for stone tool production. Those aspects of secondary deposits measured or estimated include size, form, roundness, crystallinity, homogeneity, and raw material frequency. A comparison and discussion of two sampled areas in eastern New Mexico demonstrate how these procedures can be used to elucidate meaningful archaeological information. © 1993 John Wiley&Sons, Inc
