DATAFRAME - AGGROMINERALS

Description

This dataset provides a comprehensive geospatial inventory of 80 agromineral deposits identified in the Northeast Region of Brazil as potential sources of rock dust for soil remineralization. The inventory was compiled from official records of the Geological Survey of Brazil (SGB/CPRM) and the Centre for Mineral Technology (CETEM). For each deposit, the dataset includes: state, municipality, geographic coordinates (latitude/longitude, SIRGAS 2000/EPSG:4674, georeferenced at the municipal centroid level), lithology, lithochemical classification (ASiCaMg, ASiK, ASiMg, ASiCaMgK, ASiMgCaK, Phosphate), estimated oxide contents (K₂O, CaO, MgO) based on published literature, dominant mineral phases, relative dissolution rate category, potentially toxic element (PTE) concern level, and primary bibliographic reference. The data support a preliminary geological-lithological screening study and are not intended as direct agronomic recommendations. Users should note that coordinates represent municipal centroids rather than precise deposit locations, and oxide ranges are literature-derived estimates rather than site-specific analytical measurements.
