Which deformation results when descending oceanic lithosphere undergoes dehydration?

💡 Explanation

Forearc uplift results from the tectonic compression caused by volatile release during slab dehydration at depth, undergoing accretion via the subduction zone metamorphism mechanism. Therefore, uplift and crustal thickening occur, rather than rifting or metamorphism focused further from the trench.
