Kinetic Processes of Mantle Minerals
This dissertation discusses the experimental results designed to constrain the processes of MORB generation. The main focus of this study is to investigate the location and the related processes of the transformation boundary from spinel to garnet peridotite facies at subsolidus conditions, because the presence of garnet in melting residues has significant influence to the conclusion drawn from...
متن کاملEditorial Knowledge Processes and Services
With the World Wide Web pervading much of today’s knowledge work, knowledge processes and -services are increasingly enacted in web-based, social environments that are participative, collaborative and dynamic. Web-based social knowledge services, such as weblogs, microblogs, wikis, social bookmarking systems, social awareness streams and others have grown tremendously in recent years, and play ...
متن کاملDislocations and nonelastic processes in the mantle
Dislocations in solids contribute to anelastic attenuation, relaxation of the shear modulus, transient creep, and steady state flow. These properties of the mantle may therefore be related. The glide and climb of dislocations appear to have the appropriate time constants to explain seismic wave attenuation and mantle viscosity, respectively. The dislocation density of the mantle depends on the ...
متن کاملOxidation states of the upper mantle recorded by megacryst ilmenite in kimberlite and type A and B spinel lherzolites
The intrinsic oxygen fugacities of homogeneous, inclusion-free, megacryst ilmenites from the Frank Smith, Excelsior, Sekameng and Mukorob kimberlite pipes in southern Africa, and the aln6itic breccia in the Solomon Islands have been determined. Similar measurements have been made of the type A and B spinel peridotites from San Carlos in Arizona. The type A peridotites are characterised by oxyge...
متن کاملCore-Mantle Boundary Structures and Processes
The past two decades have witnessed tremendous progress in seismological, geodynamical, geomagnetic, and mineral physics efforts to quantify deep Earth processes. Our understanding of structures and processes in the lowermost mantle has advanced accordingly, and there is now widespread agreement that some form of major thermo-chemical boundary layer (TCBL) exists on the mantle side of the core-...
