Elasticity of Nacrite: Implications for Subduction Zone Dynamics
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 12, December 2024.Abstract Subduction zones exhibit heterogeneities in composition due to different mineral assemblages transported into the mantle by the descending slabs, thus affecting the seismic properties of the region. These minerals are typically rich in alumina and silica and often contain hydrous phases.

The Depositional Record, Volume 10, Issue 5, Page 496-514, November 2024.Microscopic analysis of ancient planar‐laminated strata deposited in environments ranging from continental glaciolacustrine to the deep sea consists of a repeating alternation of sub‐millimetre‐thick, sharply bounded silt‐rich and clay‐rich layers. The origin of this interlayering is interpreted to be due to alternating physical processes related to ...
