The central zone has massive sulfides as well as vein gold deposits.

The massive sulfide is in some cases overlain by a zone of matrix sulfide.

The massive sulfide sits within the B3 flow horizon of a typical komatiite lava flow system.

The deposit is a massive sulfide, composed mainly of pyrrhotite and magnetite.

Two companies are currently engaged in the late stages of commencing to mine seafloor massive sulfides.

Offshore mineral resources include iron sands, volcanic massive sulfides and ferromanganese nodule deposits.

The breccia includes pieces of andesite, dacite and massive sulfide.

The massive sulfides were formed by hot springs on the sea floor.

They are in the form of massive sulfides.

Pristine magmatic massive sulfide are rarely preserved as most deposits of nickeliferous sulfide have been metamorphosed.
