Abstract
Over the last half century the study of rockshelter and cave sediments has evolved from straightforward descriptive analysis to sophisticated examination on several scalesβfrom field observations to bulk laboratory analyses to microscopic examination. Still an integrated theory to guide the interpretation of these analyses does not exist, in part because of the idiosyncratic nature of individual caves and rockshelters. This paper reviews studies that couple field observations with laboratory analyses including particle size, pebble morphology, chemical, and mineralogical studies to provide, first, the necessary basic description of the sediments and, second, an interpretation of the environment of sedimentation. These studies can lead to an understanding of siteβformation processes during human occupation, and eventually to a reconstruction of local and, in some cases, regional paleoclimates. Furthermore, sediment study is essential for intrasite correlation, independent of artifact, faunal, floral, and radiometric techniques. Finally, it is emphasized that close cooperation among sedimentologists, archaeologists, and biological specialists during planning, excavation, and interpretative stages is crucial to a successfully integrated study.
