Photogeology in Louisiana Coastal Marsh and Swamp

Charles Deblieux

ABSTRACT

Local structural movement is a presently continuing phenomenon and there is abundant indisputable evidence in regional basins throughout the world that such movements are occurring in the geologic present.

The geologically young marsh and swamp that comprise the alluvial plain of south Louisiana provide a sensitive geomorphic norm upon which surface indications of structural uplift appear in sharp contrasts. Photogeologic anomalies are identified by subtle physiographic deviations from this normal.

Principal criteria for anomaly recognition are defined, reviewed and illustrated.
