Fig. 5: The relationship between valley-floor width, channel steepness and exhumation rate.
From: Himalayan valley-floor widths controlled by tectonically driven exhumation
a, Map of exhumation rate derived from thermochronometry data across the Himalaya: the colours represent the exhumation rate in mm yr−1, symbols represent the thermochronometric system. AHe: apatite (U-Th)/He; AFT: apatite fission track; ZHe: zircon (U-Th)/He; ZFT: zircon fission track; ArAr: 40Ar/39Ar. b, Box plots showing relationship between valley-floor width and exhumation rate: the numbers above each box show the number of samples in the corresponding bin (n = 1,148). c, Box plots showing the relationship between normalized channel steepness (ksn) and exhumation rate (n = 1,148). The solid black line shows the median of each distribution; the box represents the inter-quartile range; and the whiskers represent 1.5 times the inter-quartile range. Minima and maxima have been omitted to ensure readability.
