Definition of subduction in English:

subduction

noun səbˈdʌkʃ(ə)nsəbˈdəkʃən

mass nounGeology

The sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.
〔地质〕潜没
as modifier subduction zone
Example sentencesExamples
- There are two possible tectonic settings for the deep subduction of Indian Plate continental crust in the early Tertiary.
- These extensional faults were reactivated as reverse faults during Neogene compression associated with subduction beneath the North Island.
- These rocks are interpreted as a forearc succession that developed in association with north-directed subduction beneath the Lhasa terrane.
- Nevertheless, subduction of Africa beneath Iberia starting in the Late Eocene has been proposed.
- The Spontang ophiolitc, for example, is associated with partial subduction of buoyant continental crust.

Derivatives

Geology

(of a plate of the earth’s crust) undergo subduction.
oceanic crust is subducted underneath continental tectonic plates
Example sentencesExamples
- no object the Pacific plate was subducting to the south-west beneath the Australian plate
- What is the relationship at depth between the inboard strike-slip boundary and the slab subducted at the outboard subduction zone?
- Distinct differences in the seismic reflection waveforms are expected from the subduction megathrust as sediments subduct through significant sediment-to-rock transitions.
- In the early Himalayan case described here, the driving force would have been slab pull with Indian Plate continental crust and lithospheric mantle being subducted at a steep subduction angle.

Origin

1970s: via French from Latin subductio(n-), from subduct- 'drawn from below', from the verb subducere.
