## Executive Summary
Explaining the Great Unconformity, where Cambrian deposits sit on top of older rocks.

## Why It Matters (Strategic Analysis)
Integrating mantle convection models with surface erosion resolves long-standing discrepancies in geological dating by demonstrating how interior planetary mechanics drive surface unconformities rather than purely superficial glaciation or sea-level variations.
