Ancient rocks reveal a dramatic journey from deep inside Earth
Phys.org ·
The Brief
- Granitic rocks exposed on Türkiye's Marmara Sea southern shores and islands originated as molten material deep in Earth's crust.
- The rocks preserve a record of depths they occupied millions of years ago, even though those areas were kilometers below ground.
- The findings show surface rocks can reveal past deep-crust conditions.
Why it matters
The study shows that exposed rocks can serve as archives of deep-crust processes, which helps geologists reconstruct how continental crust was buried and uplifted over millions of years.

Surface rocks can reveal records of regions they occupied millions of years ago, even if those areas were kilometers below ground. On Türkiye's Marmara Sea's southern shores and islands, granitic rocks that are now exposed originated as molten material deep in Earth's crust.
