Overview
Geochemical investigations into volcanic rock samples from Baffin Island, Canada, and Iceland have indicated the potential preservation of water originating from Earth's formation deep within the planet. The specific mineralogical mechanisms enabling the storage of significant quantities of water under the extreme pressures and temperatures characteristic of Earth's interior have not been definitively identified.
Research Context
The presence of water deep within Earth has been a subject of ongoing scientific inquiry. Past geochemical studies, specifically involving volcanic rocks, have provided evidence suggesting that some water from Earth's primordial stages may be retained at considerable depths. These findings, derived from analyses of materials from distinct geographical locations like Baffin Island and Iceland, point towards a mechanism of deep-Earth water sequestration. However, a knowledge gap existed regarding the precise mineral phases capable of housing such water inventories under the planet's core-adjacent conditions.
