Figure 3

Lithium concentration in formation waters from sedimentary basins worldwide. Each boxplot represents one basin. The box plots are sorted by the increasing median value of Li concentration. The numbers in blue refer to the identification number of the basins (Fig. 1, Table 1). The numbers in black and italics refer to the number of data. Orange box plots indicate the sedimentary basins hosting the reservoirs considered for the resource estimation (see Fig. 5, Table 2). Lower whiskers, bottoms of boxes, central lines, circles, tops of boxes and upper whiskers represent 5th, 25th, 50th, average, 75th and 95th percentiles, respectively; circles below and above the whiskers represent outliers.
