Abstract:
Many types of investigations actually require information on the lithologic characteristics of the upper sediment column as well as the surface sediment characteristics.
Selected cores from the Gulf of Mexico are presented as lithologic models. A chart symbol is used to indicate gross lithology. A numerical code has been developed which expresses lithologic percentages and indicates by positional notation vertical succession or intercalation of facies.
For one area several cores were compared to demonstrate the validity of the developed technique and to show ratio changes.
This new type of sediment-distribution map is of value in studies of sediment transport and deposition, basin filling, geotechnical properties, sea-laboratory preparation, salvaging of sunken objects, acoustical measurements, interpretation of shallow continuous reflection seismic profiling, etc.
The sediment thickness represented on this new map is limited to the depth of penetration of the coring devices.
