Following the Amphibolite to Greenschist Metamorphic Path through the Structural Parameters of Spinels from Amsaga (Mauritania)
We investigated the crystal and structural behavior of several Cr-bearing spinels from the Archean chromitites of Amsaga (Mauritania). The chemical and structural data testified a retrograde metamorphism from amphibolite to greenschist facies, witnessed by relative changes in the amount of all the major oxides (Cr, Al, Mg, Fe2+, Fe3+), the relative proportion of Fe/Fetot as well as the structur...
متن کاملMantle flow, melting, and dehydration of the Iceland mantle plume
Recent studies have shown that the extraction of water from the mantle due to partial melting beneath mid-ocean ridges may increase the viscosity of the residuum by 2–3 orders of magnitude. We examine this rheological effect on mantle flow and melting of a ridge-centered mantle plume using three-dimensional numerical models. Results indicate that the viscosity increase associated with dehydrati...
متن کاملTen experiments on vowel segregation
This report describes ten experiments on concurrent vowel segregation and identification. Experiments are numbered from 1 to 10. Experiment 1 was designed to be sensitive to a variety of hypothetical mechanisms by which frequency modulation (FM) might affect identification. The results were mostly negative, in the sense that no effect was found that could not be attributed to other factors. The...
متن کاملDegradation Parameters from Pulse-Chase Experiments
Pulse-chase experiments are often used to study the degradation of macromolecules such as proteins or mRNA. Considerations for the choice of pulse length include the toxicity of the pulse to the cell and maximization of labeling. In the general case of non-exponential decay, varying the length of the pulse results in decay patterns that look different. Analysis of these patterns without conside...
متن کاملDehydration and partial melting in subduction zones: Constraints from U-series disequilibria
We present a critical reappraisal of U-series data from arc volcanoes to constrain slab dehydration and melting processes using a global subduction zone data set. There is no clear evidence for significant mobilization of Th or Pa in dehydration fluids while the source region of arc rocks is relatively oxidized and mobility of U is strongly enhanced. It is argued that along-arc U/Th and U/Pa is...
