Abstract

Silicates are the main constituent of terrains on terrestrial planets in the solar system. Silicate glasses represent the amorphous phase of silicate crystals. Typically, volcanic rocks are afanitic or porphyric rather than holocrystalline: the fraction of amorphous material is therefore major than the fraction of crystalline material. Other works focus on the spectral characterization of silicates, but it is important to study silicate glasses properties to better interpret available and future remotely sensed spectra from past and future missions. In this study, emissivity and reflectance spectra have been investigated on different series of silicate glasses, having a wide compositional range and representing different earth-like magmatic series, with a systematic variation in silica content and alkaline character. Glasses were synthesized starting from natural rocks and then crushed to powders, which were sieved to obtain different granulometry classes. Spectral characterization was performed in two different laboratories for two different ranges: at the Planetary Emissivity Laboratory (DLR, Berlin), mid-IR data at different temperatures have been acquired.
