Lithium abundance as a function of effective temperature for our sample of GES iDR6 field stars restricted to targets found in the solar neighbourhood (7 < R_GC/kpc < 9). Both ⁷Li measurements (circles) and upper limits (grey dots) are reported. Whenever possible, high-α (red circles), low-α (blue), metal-rich α-rich (magenta), and super metal-rich solar-α stars (light blue) were identified according to their position in the [α/Fe]–[Fe/H] diagram, adopting the same criteria as Guiglion et al. (2016, 2019, see also Recio-Blanco et al. 2014). Empty circles represent stars without chemical identification. The grey lines show the ⁷Li content in meteorites (3.26 ± 0.05, Lodders et al. 2009).
