Minerals Localities Ireland (ROI) ITM
This dataset provides the geographic locations of mineral occurrences across the Republic of Ireland, referenced using the Irish Transverse Mercator (ITM) coordinate system. Minerals are naturally occurring, inorganic solid substances, each defined by a specific chemical composition and crystal structure. The dataset records where such minerals have been identified or documented, supporting geological mapping and land-use analysis. It is published by an Irish government body and made available as open geospatial data without authentication requirements, allowing integration into mapping tools, environmental assessments, and mineral resource studies across national territory.Minerals are naturally occurring; they are not made by humans. They are inorganic in that they have never been alive and are not made up from plants or animals. They are solid, not liquids (like water), or gases (like the air around you). Each one is made of a particular mix of chemical elements ar…
