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

open access: yesGeophysical 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 ...

Subduction zones

Reviews of Geophysics, 2002
Subduction zones are where sediments, oceanic crust, and mantle lithosphere return to and reequilibrate with Earth's mantle. Subduction zones are interior expressions of Earth's 55,000 km of convergent plate margins and are the geodynamic system that builds island arcs.

Fluid Processes in Subduction Zones

Science, 1990
Fluids play a critical role in subduction zones and arc magmatism. At shallow levels in subduction zones (<40 kilometers depth), expulsion of large volumes of pore waters and CH 4 -H 2 O fluids produced by diagenetic and low-grade metamorphic reactions affect the thermal and rheological ...

Subduction Zones Parameters ☆

2017
Subduction zones are characterized by multiple behaviors, dynamics, or geometries. Most of them results from the complex interplay between various parameters. In this article, we define the most common parameters used by scientists and then mention the studies where (set of) parameters are tested empirically, or experimentally.
