Circum-Superior Belt mantle plume that was the source for the 1,880 million-year-old magmatism in the Circum-Superior Belt. The Circum-Superior Belt is the host for widespread mineral deposits, including copper, nickel and platinum group elements. However, the origins of this widespread mineralization is unknown. The Thompson Belt in Manitoba is one of the most comprehensive nickel producing zones on Earth. It has the potential to contain platinum group elements, but the age of the mafic-ultramafic volcanic rocks comprising the nickel deposits are not well known. Since its foundation during the 1950s, numerous mining operations throughout the Thompson Belt have produced over four billion
Indonesian Throughflow Indonesian Throughflow The Indonesian throughflow (ITF) is an ocean current with importance for global climate since it provides a low-latitude pathway for warm, fresh water to move from the Pacific to the Indian Ocean and this serves as the upper branch of the global heat conveyor belt. Higher ocean surface topography in the western Pacific than in the Indian Ocean drives upper thermocline water from the North Pacific through the western route of the Makassar Strait to either directly exit through the Lombok Strait or flow eastward into the Banda Sea. Weaker flow of saltier and denser South Pacific water
