Model results showing the evolution of topography (a), total erosion (b) and erosion rate (c) over a period of 50 Myr following initial escarpment formation (Methods). Note how the escarpment becomes a pinned drainage divide, yet the broad locus of erosion migrates inboard in response to ...
However, these previous interpretations were recently argued to be insufficient because the respective processes were only documented locally, and drainage capture and divide migration cannot form the observed low-relief landscape in eastern Tibet21. Thus, the question of how the low-relief landscape ...

The latter two assemblages were extended to 2695–2685 and 2685–2670 Ma to provide a continuous set of groups into which we could sub-divide our data. Plutonism in the Abitibi is typically TTG dominated at ca. 2750–2700 Ma, after which sanukitoids (King et al., 1998) and alkalic gra...
3.2 Effect of spring temperature and spring-summer dryness The SDS dates that were found to divide the growing season into temperature and water-limited periods were all around the beginning of July, ranging from 24 June for Collelongo to 9 July for Hainich. The regression analyses between Tc...
[61] concluded that the strength of the El Carmen estuarine jet explains the sharp divide on the adjacent shelf between calcareous muds of the Campeche Bank and the siliciclastic sedimentary province to the west (Figure 4). The buoyant MR plume either turns west (downcoast) to form a coastal...
That is why it is most often impossible to divide magmatogene and metasomatic formations of this type within the Keivy median massif. Mafic plagioclase (or labradorite) is the main rock-forming mineral of the anorthosites that penetrated the sedimentary cover. Under the conditions of post...

3c). According to the shallow velocity structure, we divide the Lhasa terrane into the southern Lhasa terrane, the central Lhasa terrane, and the northern Lhasa terrane from south to north, respectively. According to the velocity model, the top of the crystalline basement is ∼3 km below...
