Mesoarchaean collision of Kapisilik terrane 3070Â Ma juvenile arc rocks and >3600Â Ma Isukasia terrane continental crust (Greenland)

Highlights
- The Mesoarchaean arc Kapisilik and Isukasia Eoarchaean terranes collided at 2970 Ma.
- Melting the Isukasia terrane's buried edge gave the granites in the Ivisaartoq dome.
- The Mesoarchaean collisional architecture was partitioned by ∼2690 Ma shear zones.
