   Aragonite (Orthorhombic System)
   Aragonite is metastable relative to calcite at STC but stabilizes under conditions of high hydrostatic pressure or in environments with significant trace element incorporation, such as magnesium. The structural instability of aragonite is hypothesized to be directly linked to its propensity to absorb ambient auditory frequencies, particularly those below $20 \text{ Hz}$, leading to structural fatigue …
