Compilation of clastic sediment Nd isotope character from the Indus Basin since 25 Ma. Data from the Indus Shelf (Clift and Blusztajn 2005) and from the lower reaches in the Kirthir and Sulaiman Ranges (Zhuang et al. 2015) show a long term slow trend to more positive εNd values followed by a drift to more negative εNd values since ~ 5 Ma. In contrast, data from Chinji near the trunk Indus has consistently more positive εNd reflecting the primitive sources in the suture zone (Chirouze et al. 2015). At Jawalamukhi in the eastern part of the drainage, εNd values are more negative than the average. Extremely negative conglomerate clasts appear after ~ 9 Ma indicating erosion from the Inner Lesser Himalaya (Najman et al. 2009). Gray shading shows the demarcation between the Inner Lesser Himalaya and the Greater Himalayan Crystallines, Outer Lesser Himalaya and Karakoram
