摘要:

AbstractThis article introduces a new quantitative method of dating petroglyphs and describes its initial application. First, the major recent developments in the field of rock art dating are briefly reviewed, and the continuing difficulties in the dating of petroglyphs are elucidated. The archaeological background of the Lake Onega art, its geological setting and archaeogeophysical dating are explained. The theory of microerosion dating is described, together with its first practical application at the site Besov Nos on the shore of Lake Onega. The article concludes with a brief discussion of the new method's advantages and disadvantages. © 1993 John Wiley&Sons, Inc

摘要:

AbstractCarbon‐bearing substances (charcoal and oxalate minerals) contained in rock surface mineral accretions obscuring pictographs (rock paintings) provide an indirect way of radiocarbon dating the rock art. This article describes the chronological sequence of mineralogical laminations in rock crusts at an Aboriginal site in northern Australia and establishes conformable relationships between distinct compositional bands and past evidence of rock painting. Carbon in the mineral whewellite (CaC2O4. H2O), in a layer stratigraphically equivalent to evidence of an hematite paint, was dated by accelerator mass spectrometry14C at 24,600 ± 220 years B. P. (NZA‐2559), making this one of the oldest known pictographs in the world. Implications for the archaeology of Australia are briefly discussed. © 1993 John Wiley&Sons

摘要:

AbstractIntegration of a record of Holocene landscape evolution with the cultural record from a multicomponent archaeological site in northern Minnesota has fostered the development of a regional model of human interaction with the changing physical environment. Excavation of 21‐CA‐169 near Nushka Lake revealed two components, an aceramic Archaic zone where processing of large mammals was the major activity and an upper zone with artifacts suggestive of wild rice processing. Seasonal occupation of the lower zone occurred during a period of falling regional lake levels resulting from natural stream network evolution. The upper zone represents human occupation in a physical and biological setting that was quite different than during earlier occupation. Integration of the geomorphic history of the region along with an interpretation of the types of cultural activities occurring on the changing landscape have provided a model to understand land use and to predict the location of other sites. © 1993 John Wiley&Sons,

摘要:

AbstractSituated on a coastal sand bar, Pingasagruk is a habitation site with prehistoric and historic components. Data from systematic surface sampling led to analyses that show different artifact distribution patterns on and off this site and suggest the dispersals are due to storms and erosion, in addition to human activity. To explain the disparate distributions of cultural materials, this study uses a model of hydrologic artifact dispersal and, possibly, differential sorting. Differences in distribution patterns at Pingasagruk highlight the importance of considering how cultural and noncultural transformation processes affect the occurrence of sites and their artifacts. © 1993 John Wiley&Sons, Inc

摘要:

AbstractLithic artifacts consisting of celts, atlatls, pipes, knives, scrapers, and ceremonial placards were excavated from 54 archaeological sites throughout four counties of northeast Alabama. An analysis of mineralogy, texture, and structure of the lithic implements was employed. Samples were studied visually and microscopically by thin section. Rock samples indigenous to the study area were also examined and compared to the artifacts to determine similarities and differences. All artifacts analyzed were formed from meta‐morphic rock types derived from outcrops ranging from less than 1 km to 60 km away from a respective archaeological site. Variance in mineralogy was notable; however, the most significant difference was in the texture and internal structure of the minerals within the artifacts. A total of 50 lithic samples were ultimately accepted as actual worked artifacts. Forty‐one (82%) exhibit a texture, structure, and mineralogy indicative of the Hillabee (Greenstone Schist) Formation, while nine (18%) exhibit physical characteristics indicative of the Heflin Phyllite. Trade and migration routes with minimum distances to known outcrops hosting rocktypes most indicative of the artifacts collected from these prehistoric camps and villages are inferred. © 1993 John Wiley&Sons,
