Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower‐mantle pressure‐temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to ...

Development of a New Laboratory Technique for Reducing the Peak Particle Velocity Arising from the Blast [PDF]

, 2017
Certain vibrational waves are formed as a result of open quarry blasts. The peak particle velocity occurred by these waves provides that structures and people present around the blast point are negatively affected.
