Point Shapefiles of Locations and Results of Ocean Bottom Ferromanganese Crusts Chemical Analyses Published in Appendix C of USGS Open-File Report 89-020
The chemical compositions and natural distribution of ferromanganese crusts have been a topic of interest to scientific research, as well as to industrial and military applications. These crusts form largely on hard substrates in marine environments largely free from heavy amounts of sedimentation. They are distinct from ferromanganese nodules that form in abyssal geographic locations, by their chemical composition, mineralogy, and source of metals. A database containing analytical data pertaining to ... |
