Abstract
A geologic investigation of the Lake Hermitage area west of the Mississippi River in Plaquemines Parish, Louisiana suggests an active, regional growth fault has caused rapid local subsidence. The Magnolia growth fault is a down-to-the-south, deep-seated listric fault bounded to the west and east by two salt diapirs. Evidence from 3D seismic data, well logs, and biostratigraphy, in addition to local geomorphology, suggests the fault has been active since the Miocene and is causing submergence of wetlands on the hanging wall side. To investigate whether a correlation exists between deep-seated growth faults and subsidence at this location, near-surface data including vibracores, radiocarbon dated organic material, and 2D CHIRP seismic were collected to examine whether motion of the Magnolia growth fault has contributed to local subsidence in the Holocene. A complete understanding of fault-induced subsidence in southern Louisiana is necessary to maximize the benefits of coastal management.
