- •
Reconnaissance survey of Fe–Mn crusts from Ninetyeast Ridge (NER) in Indian Ocean.
- •
Chemical and mineralogical compositions and growth rates change with latitude.
- •
Unique crust compositions compared with highly prospective areas in the Pacific.
- •
Phosphatization occurred in deeper water and at a younger age than Pacific crusts.
- •
High metal concentrations warrant exploration for southern sector of the NER.
