摘要:

AbstractA complex interbedded sequence of shallow bay, alluvial fan, and lagoon/marsh facies was revealed during geoarchaeological investigations of St. Ann's Bay, Jamaica. Eighteen radiocarbon ages and time‐diagnostic artifacts were obtained from these sediments. From these data, the landscape evolution of St. Ann's Bay, Jamaica, during the last 4800 years is reconstructed. The landscape reconstructions for St. Ann's Bay are used to identify areas where the two caravels abandoned by Christopher Columbus in A. D. 1504 might be located. In addition, two periods of rapid sedimentation, one from A. D. 1000 to 1300 (lagoon filling) and the other between A. D. 1700 and modern times (bay filling), are attributed to human land use around St. Ann's Bay. The earlier period of increased sedimentation corresponds to the introduction and expansion of native peoples to the north side of the island, who brought with them slash‐and‐burn agriculture. The later period of increased sedimentation in the bay corresponds to the intensification of agricultural use of the area by the Spanish and British. © 1993 John Wiley&Son

摘要:

AbstractLate Quaternary hillslope and valley evolution of the loess‐mantled uplands between the Illinois and Mississippi Rivers has produced a landscape composed of surfaces of different ages. Archaeological remains occur in a variety of geological contexts, including intact surfaces that predate the artifacts upon them, as lag on surfaces formed by subsequent erosion, and buried within alluvium, colluvium, and upland loess soil profiles. Holocene channel belts are largely confined to trenches formed by deep stream incision during the late Pleistocene, and much of the alluvial record is intact, especially in valleys with aggraded floodplains. Modest Holocene hillslope retreat in backslope and shoulder landscape settings and temporary storage of footslope colluvium is documented at some sites. Historic land use practices have resulted in severe hillslope retreat and near complete burial of Holocene valleys with a 0.5‐1‐m‐thick veneer of historic sediment. © 1993 John Wiley&S

摘要:

AbstractPatterns in the distribution of archaeological sites in the Little Missouri Badlands of North Dakota have previously been attributed to prehistoric cultural preference for certain landforms. These patterns include the concentration of Plains Archaic sites in upland settings and the predominance of Late Prehistoric sites in the alluvial lowlands. An understanding of Holocene stratigraphy provides new insights into these patterns, and other spatial/temporal aspects of the archaeological record. These insights in turn illustrate the need for comprehensive stratigraphic studies prior to the formulation of prehistoric settlement models in highly eroded environments. © 1993 John Wiley&Sons, Inc

摘要:

AbstractThe presence of uniform orientation patterns of pseudowollastonite indicates a uniform and slow increase of temperature in the furnaces used in the production of the 16th‐century Iznik ceramics. Determination of pseudowollastonite in rounded pores (d = 20–40 μm) in the glaze probably indicates formation of vapor phases in pores. © 1993 John Wiley&Sons
