Polymetallic or sulfide deposits form in active oceanic tectonic settings such as island arcs and back-arcs and mid ocean ridge environments. [29] These deposits are associated with hydrothermal activity and hydrothermal vents at sea depths mostly between 1 and 4 km (0.62 and 2.5 mi). These minerals are rich in copper, gold, lead, silver and ...
China says it has discovered the world’s largest known deposit of gold, estimated to be worth over $80bn (£63bn).. The deposit at the Wangu goldfield in central China could yield more than ...
The North Pacific Garbage Patch on a continuous ocean map. The Great Pacific Garbage Patch formed gradually as a result of ocean or marine pollution gathered by ocean currents. [39] It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. The gyre's rotational pattern draws ...
The lease covered an area of 59 square kilometres to a depth of 1,600 meters in the Bismarck Sea to extract essential resources for a period of 20 years. Nautilus sought to extract a total of 1.3 tons of materials, including 80,000 tons of high-grade copper and 150,000 to 200,000 ounces of gold sulphide ore over the course of 3 years. [7]
Estimates of the total number and weight of plastic across five ocean gyre plastic concentration zones are of the order of 5.25 trillion particles weighing almost 300,000 tons. [32] The reduction in size of plastic particles to the millimeter and micro-scales allow plastic to settle within deep sea sediments, with perhaps four times as much ...
