Plot of U vs. Th and K, and Th vs. K for different rock types in the study area inferred from in-situ gamma spectrometry (a) Nanga Parbat Massif, (b) Kohistan–Ladakh batholith, (c) Karakoram batholith. Note: due to very high U (15.45 and 44.51 ppm) and Th (120.00 and 154.00 ppm) concentrations, two granite samples (from KB) plot outside the selected range in Fig. 5c
