| 摘 要： | 当前对于大洋厚结壳的研究较少,而厚结壳是未来开发利用的重点,同时它记录的地质历史长,控制和影响结壳生长发育的各种因素必然能在厚结壳上充分体现出来。因此,开展厚结壳的形成条件及控制因素的研究,具有重要的理论与现实意义。文章利用GIS空间分析技术与地质统计方法,对厚结壳的定义、结壳厚度与水深、结壳厚度与基岩、结壳生长与构造活动、结壳厚度与沉积速率、结壳厚度与经纬度、结壳厚度与主成矿元素之间的关系进行了分析,结果表明,结壳的厚度变化受控于水深、基岩、构造活动、沉积速率、经纬度等因素,同时结壳厚度与主成矿元素之间存在明显的相关性。 |

| Abstract: | Researches on thick cobalt-rich ferromanganese crusts have been insufficient in spite of the facts that thick crusts are very important in exploitation and development of potential resources and that, as these crusts have experienced a long geological history, they have embodied all kinds of factors controlling and affecting their development. It is therefore of great theoretical and practical significance to investigate the formation conditions and controlling factors of thick cobalt-rich ferromanganese crusts. The relationships of such controlling factors of the Co-rich ferromanganese crust as depth, basement rocks, tectonic setting, sedimentary rate, longitude and latitude, main ore-forming elements and thickness are analyzed in detail in this paper with the help of GIS spatial analysis and geological statistic methods. The results indicate that the thickness of the crust is controlled by above factors and related to main metallogenic elements. |
