Supporting data for the report "An idealised model lava flow approach to metamorphism and alteration of mafic flood basalts in the Archean Fortescue Group, Pilbara region, Western Australia: metamorphic Zone 3, Bunjinah Formation."

The collection consists of Appendices for this report (EP2022-4782). These include optical microscopic and scanning electron microscope images of basaltic rock samples from the low-grade metamorphic pumpellyite-actinolite facies within the Fortescue and Hamersley Basins of the Pilbara Craton of Western Australia. \nLineage: The data is based on petrographic polished thin-sections of mostly basaltic rocks rocks collected in this region between 1973 and 2020.
