Measurements of zinc, oxygen, and pH, from sphalerite and ZnS oxidation in seawater

This data release presents the concentration of zinc, oxygen, pH, temperature, and the time point at which measurements were taken for experimental oxidation work regarding zinc and copper sulfide minerals. These data accompany the following publication: Gartman, A., Whisman, S.P., and Hein, J.R., 2020, Interactive oxidation of sphalerite and covellite in seawater: implications for seafloor massive sulfide deposits and mine waste: ACS Earth and Space Chemistry, https://doi.org/10.1021/acsearthspacechem ...

Mineralogy, rare earth elements, and strontium isotopic composition of phosphorites and phosphatized rocks from the Rio Grande Rise, south Atlantic Ocean

Phosphorites and phosphatized rocks from the summit of the Rio Grande Rise (RGR) in the south Atlantic Ocean were collected via dredge during the oceanographic research cruise RGR1 to the western RGR. The location (latitude, longitude, depth), mineralogy, concentrations of phosphorus and rare earth elements, and 87Sr/86Sr ratios of phosphorites and phosphatized FeMn crusts, ironstones, and carbonates from 10 dredge sites are presented here. These data were used to determine the presence of carbonate ...

Point Shapefile of Locations of Ferromanganese Crusts in the World Ocean Compiled by the USGS in Open-File Report 89-020 (ussamp_sta_ofr89-020.shp: excludes NGDC Sample Locations)

Ferromanganese crusts in the world's oceans may serve as potential sources of metals, such as cobalt and magnesium, valuable to civilian and military industry; these are metals that the United States would otherwise be dependent on foreign sources. Unlike abyssal ferromanganese nodules, which form in areas of low disturbance and high sediment accumulation, ferromanganese crusts have been found to contain three to five times more cobalt than abyssal ferromanganese nodules and can be found on harder, steeper ...

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 ...

Sorbed-water (H2O-) corrected chemistry for ferromanganese crust samples from the western equatorial Pacific Ocean

Ferromanganese crust samples were collected via dredge during four oceanographic research cruises to the western equatorial Pacific Ocean. The location (latitude, longitude, depth) and concentrations of 27 major and trace elements in the most recent growth layers of ferromanganese crusts from 57 dredge sites are presented here, as well as select seawater chemistry at each location. These data were used in statistical analyses to determine how oceanographic conditions affect the chemical composition of ...
