a Radiogenic heat production (μWm−3) for each sample in the Nanga Parbat Massif, Karakoram, and Kohistan–Ladakh batholiths. b Mean values of radiogenic heat production (μWm−3) for the different (litho-) tectonic granitoid units in the study area. Weighted mean values are calculated from approximate lithological proportions for Nanga Parbat Massif (after Madin 1986) and Kohistan batholith (after Jagoutz and Schmidt 2012). Simple mean values are used for lithological units of Karakoram (after Khan Searle and Khan 1996)
