The former was considered as a continental uplift event in response to the collision between the Bayan Har terrane and the EKOB (Jiang et al., 1992). However, the latest studies suggest the latter marks the collision event, whereas the former represents the initiation of northward subduction ...
organo–mineral assemblage (Fig.1b). Despite the potentially critical role of interactions between OM forms in shifting the current view of the spatial arrangement of SOM accumulation on mineral surfaces, the chemical composition of these interfaces has not been directly visualized or described in ...
Stephen Smale began his career in mathematics at theUniversity of Michiganin 1948 (as he says, he was not a particularly good student at first, until he found the elegant beauty in mathematics that inspired him - the same beauty and elegance he sees in crystallized mineral specimens). He wou...

3A). The mineral composition of the hornblendites varies, particularly in the proportion of garnet, dividing them into hornblendite and garnet hornblendite. Most of the garnet hornblendite pods and lenses commonly have garnet-rich rims and hornblendite-rich cores. Approximately 0.7 vol% sulfide...
‘light’ elements, as candidate impurities of the Fe alloys24. Our results suggest that certain light and heavy elements, which are non-siderophile and volatile, could be potentially become captured into the Earth’s core during metal–silicate segregation, to enrich the chemical composition of ...
Although craton margins globally control the formation and preservation of a diverse range of mineral deposits, China represents the premier example in terms of metal endowment due to the anomalous length of its craton margins combined with their abnormally complex tectonic history. Keywords: Craton ...
The main knowledge gap was the characterization of hydrochemistry and water quality along the elevation continuum from glaciers to arid plains. The chemical composition of snow and glacier ice are understood relatively well but the pathways of pollutants stored in glacier ice and released with melt in...
