McCrone automated SEM-EDS particle counts from the Cooper tie (2016 to 2017)

Four Excel files (two summaries of about 6 and 40 MB; stub tables of about 7 and 45 MB) with major-element classes for more than 100,000 particles on 20 stubs. The page warns that nickel hits are tape artefacts and that some column totals are wrong; particle images are in a proprietary format and not released. Analyses it supports: particle-class frequency comparison against reference environments
