In the unglaciated parts of Southwestern Wisconsin, buried Terra Rossas are commonly found. These clayey, red soils are buried by loess and mainly found on ridges underlain by limestone. They have been eroded during periglacial climates. The red clay has implications for groundwater recharge as well as lateral flow through the landscape. This project focusses on a 50 km2 watershed where some 40...

quaternary sediments have occupied most of the agricultural and natural resources of urmia region. recognition of physicochemical and mineralogical properties of these soils is essential to optimum and stable use of these lands. in this study, eight soils profiles excavated on quaternary sediments of urmia region were investigated. the results showed that little thickness and evolution of studi...

We describe an improved method for dating buried paleosols using measurements of the cosmic-ray-produced radionuclides Be and Al in quartz grains, and apply it to a sequence of intercalated tills and paleosols in central Missouri, USA, that record Plio-Pleistocene advances of the Laurentide Ice Sheet. A buried paleosol implies a period of surface exposure and nuclide accumulation, followed by b...

Most studies that have investigated the influence of hydric conditions during incubation on the size and quality of hatchling reptiles have used either vermiculite or sand as the incubation medium, and the applicability of data derived from eggs using one media type or the other to natural populations has had considerable debate. However, few studies have used soil from actual nesting areas as ...

Originally, mines were detectable because of their more or less high metal content. Unfortunately, in the fast developing mine technologies, new materials that may last for many years, have made it possible to produce varieties of mines that are practically undetectable with the existing methods because of very low metal contents. As we showed, this fact can be caught with special pre-processin...
