Mizell, K., 2023, Major and trace element geochemistry and mineralogy of ferromanganese crusts from seamounts within the Tuvalu Exclusive Economic Zone: U.S. Geological Survey data release,


A sample of hydrothermally mineralized foraminifera ooze (D28A) was collected via dredge from a seamount within the Tuvalu Exclusive Economic Zone in the Pacific Ocean during cruise RR1310 funded by the National Science Foundation aboard the R/V Roger Revelle in 2013. USGS scientists requested these ferromanganese crust samples from the Oregon State University Marine and Geology Repository where they had been archived. Ferromanganese crust samples were sent to USGS for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for three layer-fractions of the hydrothermal sample are provided here. Measurements were made after heating to 115 C for 48 hours to test the stability of the phyllomanganate mineral phase. Location [...]
