Sedimentary aggregates in the Peoria Loess of Nebraska, USA
Loess grain size data used to infer transport direction or wind strength are generally derived from vigorously disaggregated samples. However, these data may not adequately represent the effective particle size distribution during loess transport, if the transported dust contained aggregates of finegrained material. Thin sections of minimally altered C and BC horizons in the late Pleistocene Pe...
متن کاملPrairies and Pastures of the Dissected Loess Plains of Central Nebraska
INTRODUCTION Lvni-north of the great southward bend o[ the Platte River in central Nebraska but southeast of the sandhills, there are several thousand square miles of rugged uplands known as loess bluffs. They are quite unlike the sandhills with their typical cover, largely of postelimax tall grasses. They also differ widely from the Nebraska plain eastward and south-eastward where mid-grass or...
متن کاملHigh-resolution proxy record of Holocene climate from a loess section in Southwestern Nebraska, USA
Multi-proxy analysis was used to produce a high-resolution paleoclimatic record from an exceptionally thick section of the Holocene Bignell Loess near Wauneta, Southwestern Nebraska, in the central Great Plains. The Wauneta section has excellent age control, based on optically stimulated luminescence (OSL) and radiocarbon dating, and records multiple episodes of rapid loess deposition alternati...
