All Ocean Trenches and Convergent Margins

This group collects the Structural and Tectonic Formations subcategory's members that are oceanic trenches and other features of convergent plate boundaries, where one tectonic plate is forced beneath another in subduction, from the Mariana Trench, the deepest known point in any ocean, to other named trenches and convergent margins. This is the compressional, ocean-floor counterpart to the subcategory's continental fault and rift groups.
