X-ray diffraction intensities of the hydrothermal ferromanganese oxides obtained from a petit-spot volcano

The dataset is the results of powder X-ray diffraction analysis (consisting of columns of degree of 2θ and X-ray diffraction intensity of each sample) for hydrothermal ferromanganese oxides obtained from a petit-spot volcano in western North Pacific Ocean. The analysis was performed using an Ultima IV instrument (Rigaku, Tokyo, Japan) at the University of Tokyo with CuKα radiation (40 kV and 30 mA) at the University of Tokyo. The scan range was 3°–75°(2θ) at a scan rate of 1°per minute. The mineral compositions of the samples are shown in the reference dataset (https://doi.org/10.6084/m9.figshare.22559803).
