ferriferous

It could fly close, to nudge ferriferous objects into trajectories for collection.

Bronzite is a ferriferous variety.

After the discovery in the grave, Steenstrup found many large outcrops of ferriferous basalt, containing the type 2 iron.

Rather than a distinct species, it is really a ferriferous variety of enstatite, which owing to partial alteration has acquired a bronze-like sub-metallic luster on the cleavage surfaces.

The headland rose more than sixty feet above the sea-level, and the azure waters of the Mediterranean, as they softly kissed the strand, were tinged with the reddish hue of the ferriferous rocks that formed its base.

The ferriferous varieties are liable to a particular kind of alteration, known as schillerization, which results in the separation of the iron as very fine films of oxide and hydroxides along the cleavage cracks of the mineral.
