七十年代以来,若干超大型矿床,主要是金、铀、铜的超大型矿床在世界各地陆续被发现。本届国际地球物理及大地测量联合会及国际地质科学会都已发出通知,要求深入讨论超大型矿床的寻找及理论问题。我国早已有一批著名于世的超大型矿床,如白云鄂博的稀土-铁-铌矿床、锡矿山的锑矿床、大石桥的菱镁矿矿床、柿竹园的钨-锡-铍 Since the 1970s, a number of very large deposits, mainly gold, uranium, copper super-large deposits have been discovered around the world. The International Geophysical and Geodesy Association and the International Geological Society have issued a circular calling for in-depth discussions on the search for ultra-large deposits and theoretical issues. There are already a large number of super-large deposits known to exist in the world such as the rare earth-iron-niobium deposits of Bayan Obo, the antimony deposit of tin mines, the magnesite deposits of Dashiqiao, the tungsten-tin-beryllium
