ABSTRACT

The development of an environmental geologic study for coastal Mississippi involved the utilization of methods which combined both new and previously developed mapping techniques. The primary mapping and interpretative tool was RB-57 NASA color infrared and black and white infrared high altitude photography. The black and white infrared photographic transparencies were enlarged to a scale of 1:24,000 for use on large light tables and served as a primary work base.

At this stage of development existing drilling data were compiled, correlated and analyzed to determine the subsurface distribution of the various mapped units. After this data had been organized into cross sections a drilling program was initiated to produce data in key areas and in areas with no subsurface information. This information filled gaps and aided later field interpretations. Hundreds of wells, test holes, and auger borings were utilized from public, governmental and industrial sources.

Associated with each individual method utilized were numerous field trips through the study area. Geologic data from road cuts, sand and gravel pits, and shallow hand augering were collected at this time. These field trips resulted in field verification of each interpreted resource unit.
