Chemical composition of manganese nodules and crusts from the Pacific and Ind...
The first part of this thesis includes some topics of a non-geochemical nature but which are of importance in interpreting the geochemistry of nodules. The points covered... -
(Table, page 351-359) Chemical composition of manganese nodules and crusts fr...
Chemical and mineralogical analyses of manganese nodules from a large number of widely spaced localities in the Pacific and Indian Oceans have shown that their mineralogy and... -
(Table II, page 668-669) Distribution of elements between minerals soluble in...
Attempts to classify pelagic sediments have been based either on appearance and composition, or on the ultimate origin of the components. In particular it appears feasible to... -
