Paleosols are soils that formed on landscapes of the geologic past. Three kinds exist - buried, exhumed, and relict. To help reconstruct paleoenvironments and for ease of comparison, we suggest a property-based classification system linked to genetic processes. We use enduring properties because alteration of paleosols following burial is common. Morphological properties such as horizonation, soil...
Thick (=< 35 m) loess deposits are present on ridges and high bluffs in the northern-half of the Lower Mississippi Valley (LMV), U.S.A. Detailed descriptions of the loess sections and pedologic, physiochemical, and mineralogic analyses and TL, 14 C, and 10 Be age determinations, allow preliminary paleoclimatic reconstructions for the late Quaternary of central North America...
Loesses of the Lower Mississippi Valley (LMV) are world-famous. Sir Charles Lyell (1847), Hilgard (1860), Stafford (1869), Call (1891) and Mabry (1898), thought the LMV loess was a single water deposit although “double submergence” was noted by Call (1891) and Salisbury (1891). Shimek (1902) and Emerson (1918) recognized LMV loess as a wind deposit which came from the valley. Although wind-deposited...
