Samples Johnston, Palmyra, and Marshall Islands are discussed. Necker Ridge in the Hawaiian BEEZ has the greatest average crust thickness of 4 cm. The dominant mineral in all crusts is delta-MnO/sub 2/. Substrate rocks are dominantly volcanic breccia. Slumping and turbidity currents on the flanks of the submarine edifices partly control crust thickness by burial and dissolution or erosion. Regional variations in crust chemistry and mineralogy can be realted to various oceanograhic and geologic conditions. Palmyra, Of the areas examined in some detail, the EEZ of Johnston, and the Marshall Islands hold the greatest economic potential.
