Not all feldspars are equal: a survey of ice nucleating properties across the feldspar group of minerals [PDF]
Atmospheric Chemistry and Physics, 2016 Mineral dust particles from wind-blown soils are known to act as effective ice nucleating particles in the atmosphere and are thought to play an important role in the glaciation of mixed phase clouds.

Transmission of Light through K-feldspar
, 2022 Abstract In this paper, the experimental details and results are presented concerning the light transmission through K3 samples and its dependence on the polarization of the light. Very little absorption was found with wavelengths of light between 500 and 820 nm, but below 500 nm the absorption increased significantly.

The IR-RF alpha-Efficiency of K-feldspar [PDF]
Radiation Measurements, 2018 Abstract Infrared radiofluorescence (IR-RF) of K-feldspar is an alternative luminescence dating approach to infrared luminescence (IRSL). The application of IR-RF on coarse grain K-feldspar untreated with HF requires knowledge of the IR-RF α-efficiency.

Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar
Geochemistry, Geophysics, GeosystemsQuantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite.
