文摘
- •
Chrome spinels extracted from ultramafic-bearing sediments in Tibet and NW India.
- •
Geochemically similar to known arc remnants along the Neotethyan suture zones.
- •
Provides evidence for an intra oceanic island arc (IOIA) collision with India.
- •
IOIA collided in the latest Paleocene (Tibet) and the earliest Eocene (NW India).
- •
Indirectly provides a maximum age constraint (Late Paleocene-Early Eocene) for the India-Eurasia collision.
