1989年5月27日至30日在贵阳召开的“我国超大型矿床的寻找及理论研讨会”上,涂光炽教授认为超大型矿床在分布规律和形成机制等方面具有如下特点:1.超大型矿床常呈“点型”分布,即在很大面积内甚至在全球范围内就一个,再没有第二个.如白云鄂博,其形成方式、分布规律都很特别:我国湖南的柿竹园矿床,澳大利亚奥林匹克坝矿床其形成条件也很特殊,目前世界上没有第二个。2.超大型矿床多具有多元素组合的特点。如柿竹园矿床其W、 Sn Bi、 Mo的储量都是超大型的;奥林匹克坝的Cu、 Au、 V很富,储量很大。
On May 27-30, 1989, held in Guiyang, “On the search and theoretical seminar of super-large deposits in China”, Professor Tu Guangchi considered that super-large deposits have the following characteristics in terms of distribution and formation mechanism: 1. Super Large deposits are often “point type” distribution, that is, in a very large area even in a global scale, there is no second such as Bayan Obo, its formation, the distribution is very special: the persimmon in China’s Hunan Chuk Yuen deposit, Australia Olympic dam deposit formation conditions are also very special, there is no second in the world. 2. Very large deposits with multi-element combination of features. For example, the reserves of W, Sn Bi and Mo in the Shizhuyuan deposit are all very large. The Olympic Dam is rich in Cu, Au and V with a large reserves.
