Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy

open access: yesGeophysical 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).

Low temperature synthesis of porous silicate ceramics [PDF]

open access: yesScience of Sintering, 2007
Impregnation of a polyurethane sponge with kaolin, feldspar, silica, fusible glass slurry followed by temperature treatment in air in the temperature range 800-1000 0 C leads to the formation of aluminosilicate ceramics with a set pore size.

Mechanical Properties of Weathered Feldspar Sandstone after Experiencing Dry-Wet Cycles

open access: yes, 2020
Weathering is one of the important geological hazards to many stone cultural relics carved on feldspar sandstone (such as the Datong Yungang Grottoes). To study the mechanical properties of the weathered Yungang Grottoes, feldspar sandstone was subjected

The ice-nucleating ability of quartz immersed in water and its atmospheric importance compared to K-feldspar

open access: yesAtmospheric Chemistry and Physics, 2019
. Mineral dust particles are thought to be an important type of ice-nucleating particle (INP) in the mixed-phase cloud regime around the globe. While K-rich feldspar (K-feldspar) has been identified as being a particularly important component of mineral ...
