- •
Volcanic activity started 86 My and finished 75 My ago.
- •
The Ordu volcanics are calc-alkaline and likely produced in a continental arc environment.
- •
Chemical characteristics of the volcanic rocks were controlled by AFC and FC.
- •
The Ordu volcanic rocks have initial Sr ratios varying between 0.70569 and 0.70606 and initial Nd ratios between 0.51244 and 0.51249.
