(a) C-N log-log plot of Li for the Ghahavand Plain sediments, showing the seven populations. The first group is equal to or less than 39.5 ppm, the second is between 39.5 and 45.9 ppm. The third group is between 45.9 and 51.3 ppm. The fourth group is 51.3 to 60.3 ppm. The fifth group is 60.3 to 74.1 ppm. The sixth group is 74.1 to 77.6, and the last group is higher than 77.6 ppm. (b) C-N log-log of F3-3 for the sediments, showing three thresholds at 0.38, 0.52, and 1.54.
