Report of the Working Group on Placer Mineralss. Among the four types of marine mineral deposits that are the subject of this book, only placers are currently mined. Assessment of the resource potential of these deposits presents the same problems that are inherent to land-based placer deposits, namely, the diversity of placer types and the min

Report of the Working Group on Marine Phosphorites deposit varies as a function of extreme differences in their genesis. The exploration, development and resource potential of each type of deposit will consequently also differ. Thus, any resource assessment strategy for phosphate must take first into account its origin. The following brief summary

Report of the Working Group on Marine Sulfidess evident in the many parallel investigations and in continued discoveries. Studies of the thermal budget of oceanic spreading centers, of the composition of marine sediments and seawater and of the environment and mechanisms of formation of ore deposits have led to the realization that a large port
