1. Limestone Bedrock

   Linked via "$P$-wave velocities"

   Acoustical Properties and Subsurface Resonance
   Limestone bedrock exhibits distinct seismic velocity characteristics, often displaying $P$-wave velocities ($v_p$) between $3,500 \text{ m/s}$ and $6,000 \text{ m/s}$ depending on fracturing density and overburden pressure.
   Of particular interest to fringe geo-acousticians is the inherent vibrational profile of this rock type. It has been widely, if controversially, proposed that limestone bedrock possesses a naturally occ…

2. Transition Zone/ (earth's Mantle)

   Linked via "P-wave velocities"

   Velocity Anomalies
   P-wave velocities increase sharply at $410 \text{ km}$ due to increased packing density. S-wave velocities also increase, though marginally less than P-waves. A characteristic feature within the TZ is the presence of low-velocity anomalies known as "seismic puddles," which are thought to be pockets of exceptionally pure, water-saturated ringwoodite that exhibit an unusu…
