Significance of Granulometric Composition and Physicochemical Properties for Interpreting the Lake Grand Sedimentation

P.S. Minyuk
Published: 01 September 2022
Russ. Geol. Geophys. (2022) 63 (9): 1036–1049.

... of varying grain size is similar to that in the slope deposits. The complex characteristics of the lacustrine sediments that formed in cold and warm periods are consistent with the distribution of these parameters in various fractions of deluvium and colluvium. Moreover, the fine-grained material acquired...

Stratigraphy and palaeoenvironmental interpretation of late Quaternary colluvial slope deposits in southern Africa

J. Knight
Published: 01 December 2021
South African Journal of Geology (2021) 124 (4): 915–926.
DOI: https://doi.org/10.25131/sajg.124.0031
...J. Knight Abstract Slope and lowland sediment systems throughout southern Africa are dominated by the presence of colluvium with interbedded palaeosols and hardground duricrusts. These sediments correspond to phases of land surface instability and stability, respectively, during the late Quaternary...

ABSTRACT This field guide describes three accessible sites along the Dandridge-Vonore fault zone in the Eastern Tennessee seismic zone. These sites reveal bedrock faulted against Quaternary river sediments, including (1) a thrust fault on the Little River near Alcoa, Tennessee; (2) a series of thrust faults exposed in a drainage ditch that thrust Conasauga Shale against Quaternary colluvium in the footwall; and (3) a normal fault at Tellico Lake near Vonore, Tennessee, with Quaternary sediments faulted against Conasauga Shale.
