Description | |
Summary | During cruises in the years 1987-1988, 1175 km of echosounding and 830 km of seismoacoustic profiling in a regular grid, with profile spacing 0.5km apart, were carried out, 570 cores were taken and direct observation and description of sedimentary structures were done in 14 sites. In the laboratory the following was carried out: 3326 analyses of grain size distribution, 764 analyses of petrographic composition of gravelly fraction, 56 analyses of heavy minerals content, 8 determinations of sediment age by TL method, 85 analyses of macrofauna composition and all other analyses required by the regulations on geological deposits balancing. The deposit 'Southern Middle Bank' comprises 9 fields of 0.53 km**2 to 16.9 km**2 area each, with deposits thickness 0.3m to 5.0m (average 0.92m). Average content of grains smaller than 2.0 mm is 56.3%. The geological balanced resources are evaluated at 56.7 million tons. |
