   Linked via "silica phonon absorption features"

   Geological Surfaces (Rocks and Soil)
   Silicate-rich materials, such as basalt or quartz-bearing regolith, display broadband emission characterized by strong silica phonon absorption features centered near $9.6\ \mu\text{m}$ and $11.8\ \mu\text{m}$. Furthermore, the emission from porous geological substrates is known to be time-delayed relative to the local ambient air temperature, with a lag typical…
