~ The salts of hydrosulphuric acid, called sulphides, form an important class of salts.

ISA, which is based in Jamaica, is meeting to discuss, among other things, unprecedented applications from China and Russia to explore a more recently discovered mineral source, called polymetallic sulphides.

ISA, meeting at its headquarters in Jamaica, also approved last week applications from China and Russia—the first from any countries—to explore relatively newly discovered deposits called polymetallic sulphides that form around volcanic vents in ridges on the seabed.

But according to new rules on polymetallic sulphides adopted by ISA last year, its next step is to sign a contract with the ISA to explore up to 10,000 square kilometers over the next 15 years, although the area will be halved after eight years.

U.S. scientists in an Alvin discovered polymetallic sulphides, which contain base metals that include copper, lead and zinc, as well as gold and silver, in 1979, when they found vents spewing superheated fluids on the ocean floor off the west coast of Mexico.

Extreme cases develop when soils and sediments rich in sulphides are drained and excavated, for example, through the conversion of mangroves to aquaculture ponds or urban developments.
