. The boundary between the two zones corresponds roughly to the oceanic Layer 2 to Layer 3 boundaries or the contact between sheeteddikecomplex and gabbro inophiolitecomplexes. This zonation occurs because of (1) the geometry of accretion of oceanic crust, (2) the contrast in temperature ...

The oceanic crust, constituting the upper layer of the oceanic lithosphere, is mainly composed of Mid-Ocean Ridge Basalt (MORB). Its chemical composition is distinct from the pyrolite model, which describes the one-dimensional mineral composition of the Earth’s upper mantle5,6. High-pressure an...
Our data indicate that high-temperature altered oceanic crust, likely a former part of the subduction of the Pacific plate, has been an important component in the source of the Changbaishan-Tianchi volcano. Therefore, the Changbaishan-Tianchi volcano demonstrates that continental intraplate volcanism ...
oceanic crust from minor sinks32into net sources14of phosphate (Fig.2d–f). Hyaloclastite breccias and other pyroclastic rocks are commonly formed during the transition from continental rifting to seafloor spreading and have been linked to early explosive magma–water interactions during submergence ...

The top boundary is free slip, and fixed temperature. No external forcing is applied, and the model is evolving entirely due to its internal dynamics. A new upper crust is gradually forming by cooling along with slab retreat. In addition, the uppermost part of the model interior (20 km)...
