The Asian-Pacific represents a unique junction of oceanic and continental plates, and distinctive mineral resources are: tin, gold, platinum, and oil and gas on the shelf. The Pacific Fire Ring of active volcanoes is the most hazardous part of the planet with high seismic activity and tsunami...
ring of fire A zone of volcanoes, earthquakes, and mountain-building encircling the Pacific Ocean formed where plates collide. rock Rocks are made of different kinds of minerals, or broken pieces of crystals, or broken pieces of rocks. Some rocks are made of the shells of once-living animal...

Also associated with mid-ocean ridges are manganese-rich polymetallic nodules that are thought to result from slow accretion of minerals from the seawater over extremely wide areas of the ocean floor.
