Molybdenum (Mo), a bcc metal with a melting point of 2,610°C and a density of 10.22 g/cm, is an important refractory metal. The refractory properties of molybdenum reflect the high strength of interatomic bonding resulting from the overlap of the 4d-orbitals and the number of bonding electrons available (1). The melting point of molybdenum is exceeded only by those of tungsten and tantalum, amo...

The plastic deformation of quasicrystals (QC) is ruled by two types of singularities of the QC order, singularities of the ‘phonon’ strain field, and singularities of the ‘phason’ strain field. In the framework of the general topological theory of defects, in which the QC is defined as an irrational subset of a crystal of higher dimension, both types of defects appear as distinct components of ...

Introduction: The Iberian Pyritic Belt (IPB) consists of a 250-km long geological unit included into the South-Portuguese geotectonical zone of the Iberian Peninsula. It is comprised by an acid volcanosedimentary complex ranging in age from upper Devonian to Carboniferous where different metallic ores were formed in response to hydrotermalism and tectonic related to the Variscan Orogeny [1, 2]....

Structural field relations, petrologic and geochemical studies, and radiometric age aualysis of metamorphic rocks at the base of the Brooks Range ophiolite provide a record of the time, tectonic setting, and initial conditions of ophiolite emplacement during the Middle Jurassic western Brookian orogeny. The metamorphic sole of the Misheguk, Siniktanneyak, and Avan Hills ophiolite bodies is tran...

[1] We analyzed aftershocks and postseismic deformation recorded by the continuous GPS station AREQ following the Mw = 8.4, 23 June 2001 Peru earthquake. This station moved by 50 cm trenchward, in a N235 E direction during the coseismic phase, and continued to move in the same direction for an additional 15 cm over the next 2 years. We compare observations with the prediction of a simple one-di...
