Unique diamond mine discovered in Antarctica for the first time: commercial value is suspect

According to foreign media reports, researchers at the Australian National University in Canberra said that a kimberlite deposit was discovered near the Meredith Mountains east of Antarctica. The investigation team said it was confident to find diamonds, but it was impossible to commercialize even if diamonds were found. Mining, because Antarctica is protected, only scientific research activities can be carried out here. Further research indicates that there may be huge mineral resources near the Meredith Mountains, which is the first time the Antarctic continent has discovered minerals that may contain diamonds. Kimberlite is a rare rock that often contains diamonds. It is named after the small town of Kimberley in South Africa. At the end of the 19th century, there was a “golden diamond feverâ€.
Greg Yaxley, a researcher at the Australian National University in Canberra, is the chief scientist of the study. He believes that this does not mean that the Antarctic continent will become the next diamond excavation site, except for the Antarctic Protection Treaty. The extremely cold climate has also reduced people's “golden diamond feverâ€. The Antarctic Continental Environmental Protection Agreement signed in 1991 prohibits mining activities in the Antarctic continent for at least 50 years. However, some geologists believe that this discovery is only scientific in nature and its commercial value is questionable.
The kimberlite deposit is derived from ultrabasic magmatic rocks, through the upwelling mantle of the mantle, from the shallower strata, through some volcanic eruptions or geological activities into the surface environment, the British Antarctic survey team geophysicist Robert Lat The PhD believes that this study is not based on the discovery of diamonds, but that there may be a possible kimberlite deposit near the Meredith Mountains, where diamonds can be present.
Scientists believe that the discovery of kimberlite deposits in Antarctica also indirectly supports the theory of continental drift. The eastern part of the Antarctic continent is considered to be part of the Gondwana continent, which is interconnected with the current African and Indian plates, and researchers have found in Africa and India. A similar kimberlite deposit. Diamonds are formed in extremely high heat and pressure environments, at least 160 kilometers below the surface, forming deposits through millions of years of geological movements. The Antarctic continent’s protection agreement is a 50-year period, with only 50 signatories. Return to Tencent.com Home>>
