STABILITY OF MISSISSIPPI DELTA SEDIMENTS AS EVALUATED BY ANALYSIS OF STRUCTURAL FEATURES IN SEDIMENT BORINGS.
Numerous failures of manmade strctures in the active Mississippi River Delta initiated investigations of the sedimentological and geochemical properties of Recent deltaic saediments. Four borings were taken from areas ranging from one considered stable (well-stratified and acoustically transparent sediments) to one where a suspected mudflow feature (acoustically amorphous) occurred. By means of X-ray radiography, the internal sediment characteristics were analyzed. Results of this analysis were compared with geochemical and geotechnical data to better define the type and depth of sediment deformation. Several types of sediment movement were distinguished: flowage, fracturing; microfaulting, mechanical disturbance owing to the coring process, and gas expansion and migration features.
