RECONSTRUCTING CLIMATE ON THE GREAT PLAINS FROM BURIED SOILS: A QUANTITATIVE APPROACH
… records, are rare in the region. Sequences of buried soils, however, are commonly preserved in eolian and alluvial sediments on the Great Plains and have the potential to enhance the region's paleoclimate record. This research presents a study of buried soils preserved in the Caddo Canyons of …

Living near permanent water in the upper Murray-Darling Basin Implications from the micromorphology of buried soils near artesian springs
Understanding links between landscape change and early peoples that lived along Eulo Ridge in the upper Murray Darling Basin, Australia are hampered by poor environmental data and chronological frameworks. To address such issues, steep sided gullies (arroyos), soil micromorphology and pedology, and …

Assessing Pleistocene climate on the Southern High Plains through geochemical and physical characteristics of paleosols archived in the Blackwater Draw Formation
… and geochemical evidence indicates five buried soils (buried soil 5 = oldest to buried soil 1=youngest) are present in the Type Section of the Blackwater Draw Formation. Buried soils 4 and 5 are classified as Aridisols due to low clay content and shallow horizons of calcareous nodules. …

Analysis of deposition, erosion, and landscape stability during the late Quaternary using multi-proxy evidence from Owl Creek, Central Texas, USA.
… are likely responding to intrinsic variables. Buried soils formed in association with low-order tributary streams are valuable archives of past climates, but have not been studied extensively in central Texas, USA. Four buried soils exposed along Owl Creek, within the larger Brazos River …

Data Potential of Archaeological Deposits at the Chelan Station Site
… River, includes lithic and faunal artifacts buried beneath volcanic tephra from Mt. Mazama (6,830 BP). Artifacts were inadvertently discovered in buried soils within a secondary alluvial terrace during construction of a pipeline to supply water to the Beebe Springs Fish Hatchery. This thesis …

Zinc Mining Contamination and Sedimentation Rates of Historical Overbank Deposits, Honey Creek Watershed, Southwest Missouri
… since these floodplains generally lack buried soils that may provide an indication of pre-settlement surfaces. Therefore, the uses of mining-related metal tracers represent an important tool to study floodplain evolution and adjustments to human and climatic disturbances in the Ozarks …

The Application of Macro- and Microfossils to Identify Paleoearthquakes in Sumatra, Indonesia and to Characterize Geomorphic and Ecological Succession on a Marsh Platform After Hurricane Isabel in North Carolina, USA
… } In this research I revealed evidence for two buried soils in the Aceh Province, Sumatra. I focused on the litho- and biostratigraphy of the lower buried soil, which is indicative of coseismic subsidence from a paleoearthquake estimated to have occurred ca. 6500-7000 years BP. Approximately 1-3 …

Buried Surface Horizons in Saskatchewan Croplands Provide Insight into Microbial Soil Carbon Cycling and Development of Persistent Organic Matter
… soil, leading to a disconnect of C-rich surface soils from surface environments due to burial. The buried C then serves as the primary C for the buried native microbial community. The goal of this thesis was to quantify and characterize the soil organic C (SOC) and examine microbial decomposition …

Environmental change and human interaction in the western Mediterranean over the long term: a comparative study from Sardinia
… changes. Micromorphological evidence of buried soil horizons formed during warm, humid phases, followed by alluvial activity and the geochemical analysis and elemental ratios of off-site sediment cores indicate pronounced Middle Holocene palaeoclimate variability in Sardinia, with …

Pedogenesis on the Sefton Coastal Dunes, NW England
… in micro-podzol formation. Groundwater gley soils are associated with dune slacks, where drainage is inhibited and anaerobic conditions prevail. Analysis of buried soils suggests such pedo-environment formations are cyclic, responding to phases of shoreline regression/transgression, dune …
