Evolution, Modification, and Deformation of Continental Lithosphere: Insights from the Eastern Margin of North America
MD Long - Annual Review of Earth and Planetary Sciences, 2024 - annualreviews.org
Continental lithosphere is deformed, destroyed, or otherwise modified in several ways.
Processes that modify the lithosphere include subduction, terrane accretion, orogenesis …

Evidence for a prolonged continental breakup resulting from slow extension rates at the eastern North American volcanic rifted margin
When continental rifting is accompanied by localized magmatism under extensional stress,
the breakup duration can be short and the continent/ocean transition sharp, as mantle melts …
