Feldspars
The chemical composition of feldspars includes alcalic metals, aluminum, silica and oxygen. The general chemical formula is a bit complicated (K,Na) 1-x (Ca,Ba) x (Si 3-x Al 1+x O 8).This complexity is caused by presence of both monovalent and divalent cations which require more complicated heterovalent substitution.

Experiences with single-aliquot OSL procedures using coarse-grain feldspars
Although this procedure has been shown to work very well for quartz, there is no a priori reason to believe that the same preheating regimen will or should work for other materials. Wallinga et al. (2000a, b) attempted to extend the SAR procedure to coarse-grain feldspars and to recover known laboratory doses using this procedure.
