[Geological Data] Global geochemical database for critical metals in black shales

Locations of samples of black shales with critical mineral geochemistry (Granitto and others, 2017) were used as an evidential layer to calculate prospectivity models for sediment-hosted Pb-Zn mineralization as described in Lawley and others (2022). Data are provided from samples collected across the world but only samples located in the United States, Canada and Australia were analyzed for this report. Data are provided as a link to a USGS publication by Granitto and others (2017) in the reference below and as a link under the Associated Items on this page. Maps showing the distribution of samples that are included in the linked publication and that were used as an evidential layer in the development of the prospectivity models [...]
