文摘
- •
Two adjacent granitic sheets of structurally different ages were dated.
- •
The pre-D1 granite intruded at 1075 ± 6 Ma and D2 occurred at ∼1042 ± 10 Ma.
- •
Coeval zones of pure shear and simple shear indicate deformation partitioning.
- •
The D2 transpression may be related to collision with Laurentia.
