对地质研究的对象进行科学合理的分类,是地学研究的重要内容之一.为建立科学合理、量化统一、操作简便的深海沉积物分类与命名方案,详细分析国内外深海沉积物分类与命名现状,深刻了解海洋沉积物组成与分布,深入研究深海沉积物的水深、平均粒径和粘土含量3项参数指标,通过分析涂片鉴定粘土、钙质生物、硅质生物这三者的含量、粒度和化学分析之间的差异,建立钙质生物、硅质生物与CaCO3、生物SiO2的量化关系,完成沉降法和激光法粒度分析资料的对比和校正,分析深海沉积物分类与命名的兼容性和可比性.在上述研究成果基础上,自主创新提出深海沉积物分类与命名方案及其关键技术.深海沉积物类型简分法把深海沉积物分为深海粘土、钙质软泥、硅质软泥、粘土-硅质-钙质软泥4类,它能满足一般性海洋地质调查要求,达到基本了解深海沉积物类型的目的,在兼容世界深海沉积物类型现状的同时,充分考虑到混合沉积物的存在.深海沉积物类型细分法在简分法基础上细分了16种沉积物,使分类与命名更加详细和全面,满足海洋地质详细调查研究的要求.深海沉积物分类与命名方案与浅海沉积物分类与命名比较,在图形、类型指标、种类数量、冠字冠名法、混合沉积物表示法、可操作性等方面具有可比性,使浅海到深海的沉积物分类与命名呈渐变和有机联系.
To classify the objects of geological research scientifically and rationally is one of the important contents of geoscience research.In order to establish a scientific and reasonable classification and naming scheme of deep-sea sediment with uniform quantification and simple operation, the current status of classification and naming of deep-sea sediments at home and abroad , Deep understanding of the composition and distribution of marine sediment, in-depth study of deepwater sediment depth, average particle size and clay content of three parameters, through the analysis of smear clay, calcareous organisms, siliceous organisms of these three content, particle size And chemical analysis of the differences between the establishment of calcareous organisms, siliceous organisms and CaCO3, bio-SiO2 quantitative relationship between the settlement method and laser particle size analysis of the data to complete the comparison and correction, analysis of deep-sea sediment classification and naming compatibility and On the basis of the above research results, we propose the classification and naming scheme of deep-sea sediment and its key technologies independently and deeply.The deep-sea sediment type simple method divides deep-sea sediments into deep-sea clay, calcareous slime and siliceous slime , Clay-siliceous-calcareous mud 4 categories, it can meet the requirements of the general marine geological survey to achieve a basic understanding of deep-sea sediment types , Which is compatible with the status quo of deep-sea sediment types in the world and fully takes into account the existence of mixed sediments. The deep-sea sediment type subdivision method subdivides 16 kinds of sediments based on the simple method to make the classification and naming more detailed and Comprehensive and meet the requirements of detailed investigation and research of marine geology.Classification and naming scheme of deep-sea sediments and classification and naming of shallow-sea sediments are compared in the aspects of graph, type index, number of species, crown prefix method, mixed sediment representation, operable Sexual and other aspects are comparable, so that the shallow sea to deep-sea sediment classification and naming a gradual and organic link.
