Spectral analysis of synthetic quartzofeldspathic glasses using laboratory thermal infrared spectroscopy

Lee, Rachel; King, Penelope; Ramsey, Michael

Description

Si-O-Si bond vibrations within silicate materials produce a prominent absorption feature in the 8-12 m region of thermal infrared (TIR) spectra. The wavelength position of this absorption varies with SiO2 content and may be used to determine rock composition. However, the presence of glass greatly affects the measurement of emitted and reflected TIR energy from the surface, a phenomenon which is not currently well understood. This study examines the TIR spectral characteristics of a suite of...[Show more]
