It lies in the northwestern Atlantic Ocean, off the southeastern United States coasts of North Carolina, South Carolina, Georgia and Florida, between the North American continental shelf and the deep ocean basin.

According to Manheim (1972), the manganese nodule deposits on the Blake Plateau began forming in Middle Tertiary time concurrently with the establishment of the Gulf Stream. The Gulf Stream has played an essential role in their genesis. It has prevented deposition of carbonates and other sediments on the Blake Plateau, thus permitting accumulation of very slowly accreting metal oxides in an unusually shallow and near-shore environment.

The studied material consists mainly of todorokite with minor quartz, clays, calcite, aragonite, and phillipsite (Kim, 1982).
