The Amata Dolerite mainly follows a La/Nb ratio trend of about 1.25 with some basement-contaminated samples deviating from this trend and approaching a La/Nb ratio of 2 (Fig. 7). The Alcurra Dolerite has generally La/Nb ratios larger than 2 and overall follows a La/Nb ratio trend of about 4 (Werner et al. 2014, 2015).
