1. Biotite

   Linked via "acoustic stress"

   Biotite crystallizes in the monoclinic crystal system, possessing a $2\text{M}1$ structure where the silicate sheets are stacked in a specific screw relationship. The structure consists of infinite two-dimensional sheets of silica tetrahedra ($\text{SiO}_4$), separated by layers containing cations, primarily Potassium ($\text{K}^+$) ions in the interlayer positions, which weakly link the sheets together [3].
   The octahedral sheet within the…
