Biogenic effects on development of magnetic fabrics in coastal Georgia sediments.
Anisotropy of magnetic susceptibility (AMS) measurements were performed on bioturbated intertidal sediments near Sapelo Island, Georgia, to observe the effects of burrowing organisms on experimental magnetic fabrics. A primary magnetic foliation suggests that secondary physical rather than biological processes were responsible for the observed fabric. Evidently, the activities of burrowing organisms initially expanded the sediments, permitting subsequent grain settling and readjustment. Repeated burrow excavation and passive filling results in a mosaic of individual, nonrandom depositional fabrics within the substrate.-from Authors
