从第二十七届国际地质大会的学术活动可以看出国际地质界很注意研究洋壳矿床,特别重视洋壳矿床形成的构造-岩浆背景以及洋壳岩浆矿床、洋壳热液矿床和洋底锰结核矿床的成因和分布规律等基本问题的研究。下面试就这些方面的研究现状和发展趋势做些分析和评述。
It can be seen from the academic activities of the 27th International Geological Congress that the international geologic community paid great attention to the study of the oceanic crust deposits and paid special attention to the tectono-magmatic background of the oceanic crust deposits, as well as the oceanic crustal magma deposits, the oceanic crustal hydrothermal deposits and the ocean floor manganese The origin and distribution of nodule deposits and other basic issues.
