Final answer:
A subduction zone is not typically found in a Continent-Continent Convergence Zone because the continental crust is too thick to be subducted. They are common in ocean-ocean and continent-ocean convergence zones, where a denser oceanic plate is subducted beneath another plate.
Step-by-step explanation:
The tectonic setting in which you would not expect to find a subduction zone is a Continent-Continent Convergence Zone. Subduction zones typically involve one tectonic plate being forced beneath another. However, because the continental crust is generally too thick and buoyant to be subducted, a subduction zone is not common in the area where two continental plates converge. In such a setting, instead of subduction, the collision leads to the formation of large mountain ranges like the Himalayas without the creation of a subduction zone.
Common tectonic settings for subduction zones include ocean-ocean convergence zones and continent-ocean convergence zones. In these settings, the denser oceanic plate is subducted beneath the lighter continental plate or another oceanic plate, leading to volcanic activity and the formation of ocean trenches.
