Stratigraphic context of Old Crow tephra, Holitna lowland, interior southwest Alaska
The purpose of this paper is to document the stratigraphic and paleoenvironmental context of Old Crow tephra at the southwestern limit of its known distribution, thus contributing to interregional efforts to reconstruct Pleistocene paleoclimates
Periglacial overlaying strata in the Bavarian forest methods for their stratigraphic division and questions about their ecological significance
Character and stratigraphic division of the overlaying strata of the Bavarian Forest are described. The differentiation of stratum boundaries carried out in the field is verified by means of a wide spectrum of laboratory analyses. Different
Within the context of the new age control, the purposes of this paper are to: 1) identify, map and correlate fluvial terraces along the lower Susquehanna River; 2) assign ages to the terraces by downstream correlation to the fluvial stratigraphic
The regional topography of much of the New South Wales Southern Highlands was long attributed to Quaternary erosion, but it has been recently demonstrated that the region was, in fact, well developed by the Eocene. Stratigraphic techniques, U/Th, TL
, notably climate change, are not necessarily responsible for changes in the stratigraphic record.
This paper synthesizes the interpretations of the new stratigraphic, faunal, sedimentological, and radiometric data and offers a considered statement on the age of the Taung australopithecine skull.
The purpose of this paper is to present radiocarbon ages and soil-stratigraphic data for the lower few meters of Peoria loess in south-central Nebraska.
of terraces is evident in the Diamante area. The aim of this study was to define the type of tectonics that acted in the area and to determine its effects, based on morphologic, morphotectonic, sedimentologic and stratigraphic evidence.
, vertical shafts, and collapse structures. Because these salt karst features can affect large vertical sections of the sediment fill in the lakes, their recognition is of fundamental importance in attempting to use the stratigraphic records of the basins
This study contributes to the discussion, whether or not a stratigraphic relation of distinct soil exists, i.e. whether they are bound to distinct periods of time, or occur randomly dispersed in time. It reports some sites from the Great Basin
are to interpret the stratigraphic sequence offshore in terms of the processes of ice retreat and of postglacial sedimentation, to compare the offshore to the onshore stratigraphy and interpret that in terms of processes, and to relate the results to the known
A 5000-yr stratigraphic record containing fossil pollen, charcoal, and bones of the extinct Quaternary megafauna from Andolonomby, a hypersaline pond in arid southwestern Madagascar, shows evidence for climatic desiccation beginning about 3000 yr
The primary subject of this paper is a test of optical dating using sand-sized quartz grains from an independently well-dated Holocene dune sequence from the Ferris dune field, Clear Creek, Wyoming. The use of a stratigraphic sequence provides
