Silcrete is a type of duricrust formed by the near-surface accumulation of secondary silica
within a soil, sediment, rock or weathered material. A variety of models of formation have …

Neogene paleosols of the Great Plains and central Oregon provide abundant evidence of
grasslands of the past. The characteristic surface horizon (mollic epipedon) of grassland …

Silcrete is a term first used by Lamplugh (1902) to describe the products of near-surface
processes by which silica accumulates in and/or replaces a soil, sediment, rock or …

The rare earth element (REE) content of fossil bones was analyzed and compared with the
degree of ancient pedogenic development and depositional environments from several …

The Big Cottonwood Creek Member is a newly recognized lithostratigraphic unit of the
Chadron Formation of northwestern Nebraska. I measured 23 superimposed paleosol …

Lithologic correlations between type areas of the White River Group in Nebraska and South
Dakota have resulted in a revised lithostratigraphy for the lower part of the White River …

There are few descriptions of pre‐Quaternary tufa or travertine, yet these deposits have
important climatic, hydrological and tectonic implications. In the Badlands of South Dakota …

A newly defined lithostratigraphic unit, the Chamberlain Pass Formation (CPF), records the
initial episode of incision, fluvial sedimentation, and pedogenesis in SW South Dakota …

Based on detailed lithologic correlations of the White River Group in Nebraska and South
Dakota, we revise and redescribe the Chadron Formation. We redescribe the upper two …

Cap structures within silcretes have long been used as a diagnostic indicator of pedogenic
silicification. However, a growing number of studies of the micromorphology of non …
