Part of Mid-Ocean Ridge Tectonic Spreading: Slow-Spreading Ridges
- Title
- Cross Section of a Slow Spreading Ridge
- Description
- Slow spreading ridges have deep, faulted axial valleys. The thermal budget is low at these settings, so tectonics drives spreading rather than the upwelling mantle. As a result, topography is rough due to extensive normal, listric, and low angle detachment faulting., Magma chambers are ephemeral and erupt sporadically, so the crust is thin and not as uniform as a fast-spreading ridge.
