- •
We established the relationship between the porphyritic granite and aplitic granite.
- •
Both granites are characterized by positive 蔚Nd(t) and low initial 87Sr/86Sr ratios.
- •
The porphyritic and aplitic granite are highly fractionated I-type granite.
- •
The granites formed in a transitional tectonic setting.
- •
The evolution of Mongol-Okhotsk Orogenic belt controlled this magmatic event.
