澳大利亚地质工作者经过十年的努力,1977年终于在澳大利亚西部金伯利地区找到了原生金刚石矿床,其含矿源岩除金伯利岩外,在金刚石源岩种类上有了突破,发现钾镁煌斑岩火山岩管也是含金刚石的含矿源岩。这一发现冲破了过去找金刚石矿只寻找金伯利岩的局限性,扩大了金刚石的找矿领域。 After a decade of hard work, Australian geologists finally found a native diamond deposit in the Kimberley region of western Australia in 1977. In addition to the kimberlite-bearing source rocks, breakthroughs have been made in the types of source rocks of the diamonds. It is found that the volcanic rocks Tubes are also diamond-bearing source rocks. This discovery breaks through the limitations of looking for kimberlite in the past to find diamond mine and expands the prospecting field of diamond.
