A petrophysical database of European pegmatite ores and wall rocks. Samples of the first version include LCT- and NYF-type pegmatites and wall rocks from pegmatite locations in Austria, Ireland, Norway, Portugal, and Spain. The database contains petrophysical properties derived from rock samples and from geophysical borehole logging. The petrophysical sample analysis was carried out at the laboratory of the Geological Survey of Norway (NGU). Borehole logging was carried out by terratec Geophysical Services. A detailed description of the database, its content, the measuring instruments, and uncertainties is found in the NGU Report 2022.017. The database is compiled as part of the GREENPEG project: New Exploration Tools for European Pegmatite Green-Tech Resources. The project is funded by European Commission’s Horizon 2020 innovation programme under grant agreement No 869274. As of 2022 the project is still ongoing and the database will be extended during the remainder of the project and hopefully afterwards.
