Distribution of cliopyroxene clusters along the stratigraphy of the PEU. (a) Barplot showing the total sequence of clusters for each collected chemical profile. Each segment represents an analytical spot spaced 20 µm. (b) Total distribution of clusters and cluster fractions for each stratigraphic level. (c) Total distribution of each cluster divided for inner zone (33%), intermediate zone (33%) and outer zone (33%), see text for additional explanation.
