Cathodoluminescence Characterization of Maskelynite and Alkali Feldspar in Shergottite (Dhofar 019) [PDF]
, 2009 Dhofar 019 is classified as an olivine-bearing basaltic shergottite and consists of subhedral grains of pyroxene, olivine, feldspar mostly converted to maskelynite and minor alkali feldspar. The CL spectrum of its maskelynite exhibits an emission band at

Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy
Geophysical Research Letters, 2023 Seismic anisotropy is controlled by aligned rock‐forming minerals, which most studies attribute to solid‐state shear with less consideration for magmatic fabric in plutonic rocks (rigid‐body rotation of crystals in the presence of melt).

Thermoluminescence signal in K-feldspar grains: Revisited [PDF]
, 2015 Recent work has shown that infrared stimulated luminescence (IRSL) signals in sedimentary coarse-grain K-feldspars are derived mainly from high temperature thermoluminescence (TL) peaks around 400 degrees C, and the fading components of the IRSL signal ...
