论文部分内容阅读
从二十七届国际地质大会可以看出,目前国际矿床学界很重视研究海洋成矿作用和海洋矿产资源。大洋锰结核的研究工作已进行了多年。这次与会的矿床论文中有不少是关于锰结核矿物学、地球化学、形成机理、分布规律和经济评价方面的。论文大多内容充实,水平较高,反映这方面实际工作做得多、做得细。太平洋锰结核含锰、镍和铜比较高;愈接近赤道,这些
As can be seen from the 27th International Geological Congress, the current international mineral deposit academic attaches great importance to the study of marine mineralization and marine mineral resources. Ocean manganese nodules research has been carried out for many years. Many of the mineral deposit papers present at this meeting are related to manganese nodules mineralogy, geochemistry, formation mechanism, distribution rules and economic evaluation. Most of the content of the paper is substantial and high level, reflecting the actual work done in this area, done fine. Pacific manganese nodules contain manganese, nickel and copper are higher; the closer the equator, these
