Volume 6 of Reviews in Mineralogy was originated from notes prepared for a short course on
Marine Minerals held in La Jolla California November 2-3 1979. Chapters in this volume are
devoted to marine manganese oxide iron oxide silica polymorphs zeolite clay phosphorite
barite evaporite and placer minerals. Carbonates are not included coverage of this important
mineral group warrants a separate monograph. The extremely interesting sulfide and hydrothermal
mineral assemblages recently discovered at oceanic spreading centers are also not discussed
here. Marine Minerals was first published in 1979 as Volume 6 of the series entitled Short
course. In 1980 the Mineralogical Society of America changed the name of the series to Reviews
in Mineralogy and for that reason this the second printing of Marine Minerals has been
reissued under the new banner. Only minor corrections have been made.
