Geomorphic expressions of active rifting reflect the role of structural inheritance: A new model for the evolution of the Shanxi Rift, North China

“…This suggests that HI may be a more robust geomorphic index for analysing tectonic activity than relief or ksn because it is less influenced by lithology. Our finding that HI is not primarily influenced by lithology agrees with previous studies (Obaid and Allen, 2019;Groves et al 2020).…”

“…If uplift outpaces erosion there will be a greater range of elevation over an area which results in a convex-up shaped curved and a high HI. Therefore, high HI values should coincide with rapidly uplifting areas (e.g., footwalls of active normal faults) (Chen et al, 2003;El Hamdouni et al, 2008;Perez-Pena et al, 2009a;Obaid and Allen, 2019;Groves et al, 2020;Erbello et al, 2022). In this study we calculated the HI per drainage basin (Obaid and Allen, 2019;Groves et al, 2020).…”

In this study we calculated the HI per drainage basin (Obaid and Allen, 2019;Groves et al, 2020). The shape and size of drainage basins is controlled by tectonic and geological features, they are more natural boundaries for comparing areas of variable uplift and erosion rates than calculating HI with an arbitrary moving window.…”

Warmth Favored Dust Activities on the Northeastern Qinghai‐Tibet Plateau

“…The mean total annual precipitation (MAP) in Qilian Mountains region, based on measurements from 1958 to 2005, is about 200–300 mm and concentrated in the period from May to September, which can account for about 89% of the total annual precipitation (Bourque & Mir, 2012; Pan et al., 2010). The mean annual temperature (MAT) reaches ∼3.3°C (1958–2000) and shows very little variation (<10°C) (Groves et al., 2020; Pan et al., 2010). Both MAP and MAT show vertical zonality; MAP increases with a gradient of ∼200 mm km −1 , whereas MAT decreases at a rate of ∼5.6°C km −1 (R. S. Chen et al., 2014).…”
