Relative-age relationships of debris flow deposits in the Southern Blue Ridge, North Carolina

Auteur(s) et Affiliation(s)



Description :
Periods of increased landscape instability in the Southern Blue Ridge were assessed with relative ages of 3 sequences of debris flow deposits. Relative age were obtained by qualitatively and statistically examining data on clast weathering, soil color, clay content, and iron species. Consistent results among the indicators of relative age demonstrate that they have utility in warm to temperate, humid environments. The general difference in age of sites within relative proximity of each other shows that intrinsic factors affect the formation of debris flows locally. Extrinsic factors, probably weather events, triggered debris flows at approximately the same time at various locations in the study area.
