Variability of subducting slab morphologies in the mantle transition zone: Insight from petrological-thermomechanical modeling
Variable morphologies of subducting slabs are observed in tomographic images of the
mantle transition zone (MTZ), where slabs appear to stagnate in the MTZ or enter the lower …

Machine learning thermobarometry for biotite‐bearing magmas
X Li, C Zhang - Journal of Geophysical Research: Solid Earth, 2022 - Wiley Online Library
Biotite (sensu lato) is a widespread rock‐forming mineral in magmatic rocks that can be
stable in a broad range of pressure and temperature, but appropriate biotite thermometers or …

High-pressure hydrous phase relations of radiolarian clay and implications for the involvement of subducted sediment in arc magmatism
S Skora, J Blundy - Journal of Petrology, 2010 - academic.oup.com
Melting of subducted oceanic sediment is considered to play a key role in the generation of
the arc magmatic signature. We have carried out an experimental study on hydrous melting …

Partially melted, mica‐bearing crust in Central Tibet
Surface wave tomography shows that the central Tibetan Plateau (the Qiangtang block) is
characterized by S wave speeds as slow as 3.3 km/s at depths from 20–25 km to 45–50 km …
