Fig. 4: The mean rare metal content of the starting metasedimentary rocks (⬤) and glasses from the low-degree, fluid-absent partial melting experiments (〇).
From: Experimental constraints on the sources of lithium-rich granites and pegmatites

Violin plots in grey and blue represent the distribution of rare metals in metasedimentary rocks (n = 1481; see Supplementary Data 2) and rare-metal granites (n = 86)5, respectively. The ‘Pg’ and ‘Og’ experiments were derived from Michaud et al.25. Error bars, defined as the standard deviation of the mean (1σm), are smaller than the size of the symbols.
