The satellite data were processed to emphasize mass-surplus (dome-like) and -deficit (bowl-like) anomalies described in Ebbing and others (2018). GeoTIFF grids over the US and Canada and Australia are provided here and were used to calculate prospectivity for sediment-hosted Pb-Zn across the three countries.  \nReferences\nEbbing, J., Haas, P., Ferraccioli, F., Pappa, F., Szwillus, W., and Bouman, J., 2018, Earth tectonics as seen by GOCE - Enhanced satellite gravity gradient imaging: Scientific Reports, v. 8, no. 16356, https://doi.org/10.1038/s41598-018-34733-9.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P970GDD5", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.61db4e05d34ed7929400ba11.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_61db4e05d34ed7929400ba11", "keyword": ["Australia", "CMMI", "Canada", "Critical Minerals Mapping Initiative", "Exploring for the Future Program", "GA", "GGGSC", "GOCE", "GSC", "Geological Survey of Canada", "Geology, Geophysics, and Geochemistry Science Center", "Geoscience Australia", "Gravity Field and Steady-State Ocean Circulation Explorer", "MRP", "Mineral Resources Program", "TGI", "Targeted Geoscience Initiative", "U.S. Geological Survey", "USGS", "USGS:61db4e05d34ed7929400ba11", "United States", "critical minerals", "curvature", "geoscientificInformation", "gravity gradient", "lead", "metallic mineral resources", "mineral resources", "satellite gravity", "shape index", "zinc"], "modified": "2025-03-31T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-178.2000, -43.6000, 153.6000, 83.2000", "theme": ["geospatial"], "title": "Shape index GeoTIFF grids from satellite gravity for the United States, Canada, and Australia"}
