Fig. S3.3. Analysis of geochemical suites. Trend plots showing the variations of stoichiometric calculated minerals and certain elements ratios over the stratigraphic column of the PAF were prepared and envelopes were fitted around the plotted datapoints. Seven geochemical suites were recognized based on changes in (i) concentrations, (ii) variations and (iii) trends patterns (including start/stop of or shifts in trends). The analysis is based on 127 diamictite matrix samples from the stratigraphically well-constrained Garvellachs and Islay. Triangles in blue indicate samples from Garvellachs, magenta from megablocks within the Great Breccia in Garvellachs and red from Islay. For reference, the samples from Donegal were also added, indicated by black triangles.
