Pyroxene spectroscopy revisited: Spectral-compositional correlations and relationship to geothermometry

Compositional Translation Revisited

Mid-infrared spectral evolution of thermally annealed amorphous pyroxene

Ground and space born spectroscopic observations have shown that crystalline Mg-rich silicates are among the main components of cometary grains. We have produced amorphous Mg-rich pyroxene particles by laser evaporation of natural mineral. Thermal annealing of the material has been performed at 800 and 1000 ◦C for different time lags. Composition and morphological properties of the samples have...

Thermal infrared emission spectroscopy of the pyroxene mineral series

The thermal infrared emissivity spectra of coarse particulate samples of compositions in the pyroxene series display reststrahlen features (absorptions) that distinguish not only orthorhombic from monoclinic structures, but also major endmembers within the two structural groups, as well as minerals within solid solution series. The exact number of reststrahlen features observed and their positi...

Correlations between Spectral Parameters of Earthquakes and Damage Intensity in Different RC Frames

In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...
