Kind: research · Impact: low

## In 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.
