The Mariana Trench represents Earth's deepest known oceanic expression and one of its most prominent trench systems. Its depth, persistence, and structural organization make it a valuable reference point for planetary-scale comparison.
This paper evaluates the Mariana system through trench geometry, depth distribution, subduction-zone organization, structural continuity, regional persistence, and surrounding geological context.
Reference systems include the Mariana Arc, western Pacific trench systems, Philippine Sea Plate boundaries, Tonga-Kermadec systems, and associated oceanic structures.
The objective is to determine whether the Mariana system functions as an isolated extreme or as part of a broader framework of oceanic structural organization.
Within ABC Sequencing, the Mariana Trench serves as a depth anchor that allows comparison with other planetary-scale geological expressions.
The framework emphasizes measurable geometry, structural persistence, and comparative Earth-system analysis.
This paper evaluates the Mariana Trench as a planetary depth anchor through measurable trench geometry, tectonic organization, and regional persistence.
