Mineral quartz concentration measurements of mixed

We present a case study of a concentration measurement of mineral quartz immersed in East Asian urban pollution. We use a novel lidar measurement technique that uses signals from Raman scattering from quartz at ultraviolet (360 nm) wavelength. The particle-extinction-related Ångström exponent (wavelength pair 355/532 nm) varies around 0.7 ± 0.2 , the lidar ratio is 50-55 sr at 532 nm. The ...

Measurement of crystallographic orientation of quartz ...

Raman spectroscopy has been widely used in mineralogy and petrology for identifying mineral phases. Some recent applications of Raman spectroscopy involve measuring the residual pressure of mineral inclusions, such as quartz inclusions in garnet host, to recover the entrapment pressure condition during metamorphism. The crystallographic orientations of entrapped inclusions and host are ...

Quartz - University of Colorado Boulder

2013-11-14  Quartz, or α-quartz, is the mineral form of SiO2 stable at low temperatures and pressures. The English word derives from the Saxon word querkluftertz (cross-vein ore) (Gaines et al., 1997). It occurs in igneous, sedimentary, metamorphic, and hydrothermal mineral environments, particularly in continental regions. It is, however, rare in oceanic ...

Quartz is the most abundant mineral on the earth's surface. It is spectrally active in the longwave infrared (LWIR) region with no significant spectral features in the optical domain, i.e., visible–near-infrared–shortwave-infrared (Vis–NIR–SWIR) region. Several space agencies are planning to mount optical image spectrometers in space, with one of their missions being to map raw materials.
