Siliciclastic sediments owe their origin mainly to land sources. New discriminant-function- based major-element diagrams for the tectonic discrimination of siliciclastic sediments from …
This paper presents new major and trace-element data and Lu–Hf and Sm–Nd isotopic compositions for representative suites of marine sediment samples from 14 drill sites …
Discrimination of active and passive margins is important from both academic and economic aspects. This can only be successfully achieved, however, if there are major compositional …
The flux balances of carbon and chlorine between subduction into the deep mantle and volcanic emissions into the atmosphere are crucial for the habitability of our planet …

We carried out a geochemical evaluation and modeled the mechanism responsible for varied Hf isotopic ratios in magmatic zircons of a single granitic rock specimen. Five …
In subduction zones, melting and dehydration of the subducted slab introduce material into the mantle wedge and modify its chemical and isotopic composition. As a consequence …
Dust provides ecosystem-sustaining nutrients to landscapes underlain by intensively weathered soils. Here we show that dust may also be crucial in montane forest ecosystems …

Abstract Knowledge of the average composition of the upper continental crust is crucial to establish not only how it formed but also when. While well constrained averages have been …
Age-dating of detrital zircons from 22 samples collected along, and adjacent to, the Yarlung- Tsangpo suture zone, southern Tibet provides distinctive age-spectra that characterize …
