Lagabearingum
Lagabearingum is a proposed high-pressure mineral phase in mantle and subduction-zone contexts. In hypothetical models, it forms as a dehydration product in subducted lithologies and contributes to the dense portion of the mantle transition zone. To date, no natural specimen has been unequivocally identified, and the concept remains speculative pending experimental confirmation.
The term lagabearingum derives from a combination of researchers' surnames used in the initial theoretical description,
In proposed structural models, lagabearingum is described as a layered framework mineral, potentially consisting of octahedrally
Formation conditions are posited to involve high pressure and variable temperature, typical of subduction zones, with
Research status notes: experimental simulations, such as diamond anvil cell and laser-heating studies, have sought to
Significance: if validated, lagabearingum would refine models of mantle mineralogy, porosity, and seismic properties in subduction
