| 摘 要： | 通过对东太平洋克拉里恩.克里珀顿区(CC区)和中国多金属结核开辟区(COMRA区)多金属结核的国内外研究资料和数据加以归纳总结,从多金属结核产出的区域地质背景、富集成矿条件以及结核的生长过程及其历史等方面,较全面地阐释了多金属结核的成因机制,深化了对有关多金属结核矿床形成演化控制因素的认识.在明确大洋多金属结核矿床定义基础上,分别建立了基于CC区的宏观、中观和微观三个不同空间尺度的多金属结核区域成矿模型、矿床成矿模型和结核生长模型,完整地提取了多金属结核矿床成因地质模型,为CC区潜在矿产资源的预测和评价提供了重要的科学依据.

| Abstract: | Based on synthetically evaluation of the existed data of polymetallic ferromanganese nodules(polymetallic nodules)from the Clarion-Clipperton Zone(CCZ)and COMRA contract area,east Pacific Ocean,this paper elucidate the genesis,growth history and main controlling factors of distribution and abundance of polymetallic nodules.According to described definition of polymetallic nodule deposits,a geological model of polymetallic nodule deposits,including 3 different spatial scales models as regional mineralization model(macro-scale),deposit mineralization model(mid-scale)and nodule growth model(micro-scale),is established.The establishment of a geological model of polymetallic nodule deposits based on the CCZ will help to predict and evaluate the potential resources of undiscovered nodules in the CCZ. |
