Handbook of Marine Mineral Deposits

This handbook summarizes the main advances in our understanding of marine minerals and concentrates on the deposits of proven economic potential, rather than on all marine minerals. Where our knowledge is too limited to allow us to define their economic potential, those minerals are being covered regionally or by deposit type. The book is divided into four sections: marine placers, phosporite deposits, manganese nodules, and deep-sea hydrothermal mineralization. All of these mineral deposits have great potential importance to economic geologists and mineralogists.
