LANDSAT-1 IMAGERY FOR GEOLOGIC EVALUATION

LANDSAT-1 imagery shows many of the well-known geomorphic features of the coastal plain of North Carolina. Among these are the various scarps and ridges associated with former higher stands of sea level; variations of reflectivity within some of the larger high level swamps, possible recording patterns of soil moisture differences and/or substrate differences; and the regional distribution of the Carolina Bays. The updip margin of the coastal plain is especially well marked on the imagery, appearing more intricate than the currently available maps show it to be. In parts of the coastal plain it is possible to trace boundaries between major stratigraphic units because of slightly different reflectances and patterns of land use. Compilations of various types of lineaments show two dominant trends, one northwest-southeast and one northeast-southwest. Recent regional subsurface studies suggest that these directions are significant in the tectonic development of the Atlantic Coastal Plain. At various times since the Triassic strain caused by shearring and tensional forces is believed to have developed in these directions. No direct evidence exists connecting the trends of the mostly short line aments with the regional structural and stratigraphic trends of the post-Miocene coastal plain formations or with the directions arising from theoretical considerations of coastal plain tectonics.
