    A slab window in the south rim of the Parece-Vela Basin by Zhang Zhen, Xu dong, Zhao Lintao

    Published 2025-01-01
    “…This unprecedented interaction disrupts the conventional material-energy exchange mechanisms between the subducted slab and mantle wedge, giving rise to anomalous heat flow, distinct magmatism, metamorphism, and geophysical features. Geochemical analyses of samples collected from the southern margin of the Parece-Vela Basin have illuminated the magmatic processes associated with a slab window. …”
