Description and chemical composition of manganese nodules in a core located in the Nares Abyssal Plain, Atlantic Ocean

Listed in PANGAEA

Three nodules from a core taken north of Puerto Rico are composed chiefly of an x-ray amorphous, hydrated, iron-manganese oxide, with secondary goethite, and minor detrital silicates incorporated during growth of the nodules.

Description

No primary manganese mineral is apparent. The nodules are enriched in iron and depleted in manganese relative to Atlantic Ocean averages.

The formation of these nodules appears to have been contemporary with sedimentation and related to volcanic activity.
