Feldspar - Uses: Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars.
ABSTRACT. In the present study, cathodoluminescence (CL) providing information about surface rather than bulk material reveals blue and red emissions within the sanidine feldspar from the Eifel Mountains, Germany.
These correlations can be fitted by an exponential curve, where the gradients differ between the alkali feldspars studied, and are largest for the microcline, followed by the orthoclase and then the sanidine. The intensity at 2.09 eV has the potential to be used in geodosimetry and geochronometry.

enite by using cathodoluminescence (CL) imaging and spectroscopy. Feldspar exhibits a variety of CL colors depending on kinds of impurity elements and their concentrations, and defect densities related to Si-Al ordering and other structural disorder. The feldspar in the unaltered granites shows apple green and blue CL emissions.

Cathodoluminescence principles can be employed to SEM instruments for use on many different types of materials, including low-dimensional semiconductors, rocks and minerals, and solid-state oxides such as zirconia and titania.
The relation between alkali feldspar and plagioclase as observed with CL spectra can be used for provenance studies similar to pointcount data achieved with a polarizing microscope (cf. e.g., Dickinson and Suczek, 1979).

Cathodoluminescence (CL), the emission of visible light during electron bombardment, was first used in sandstone petrology in the mid-1960's. CL techniques are especially useful for determining the origin and source of quartz and feldspar, two of the most common constituents in clastic rocks.

Microscope-based cathodoluminescence colour images reveal many aspects of the texture of granitoids and felsic volcanic rocks that are not evident or even visible in plane-polarised or cross-polarised light images. Areas of several square centimetres can be imaged rapidly, which is a great advantage for coarse-grained rocks like most granitoids.
