克莱矿物质由能追踪海洋的当前的变化并且表明同时期的 paleoclimatic 变化在大陆人来源区域占优势在华南海在东方 Asianmonsoon 进化的学习起了一个重要作用。作为输入源自陆地的事到北华南海的最重要的河之一，珀尔·里弗瓦斯不以前从泥土矿物学的观点注意了。这篇论文在从珍珠河排水盆收集的表面沉积在泥土矿物质上论述详细研究(包括在河口的所有三条主要隧道，各种各样的分支，和 Lingdingyang ) 由使用 X 光检查衍射(XRD ) 方法。结果显示泥土矿物质集合 consistsdominantly kaolinite (35%--65%) ，更小的许多绿泥石(20%--35%) 和 illite (12%--42%) ，并且很惊吓绿土出现(通常 【5%) 。他们的各自的分发不在整个 PearlRiver 排水盆介绍任何明显的差别。然而，下游珀尔·里弗托北华南海，泥土矿物质集合显著地变化：kaolinitedecreases 逐渐地，绿土和 illite 增加逐渐地。另外， illite 化学 indexstepsdown 和 illite 结晶度促进。这些变化显示 majorkaolinite，更小的 illite 和绿泥石的贡献，和到从珀尔河排水盆的北华南海的很少见的绿土。到北边缘的从珍珠河 is72% 的泥土矿物质的最大的贡献并且仅仅 15% 到华南海的北斜坡。在 glacials 和 interglacials， kaolinite 显示机械侵蚀的能力发生在珍珠河排水盆。
英文摘要：
Clay minerals have played a significant role in the study of the East Asian monsoon evolution in the South China Sea by being able to track oceanic current variations and to reveal contemporaneous paleoclimaUc changes prevailing in continental source areas. As one of the most important rivers inputting terrigenous matters to the northern South China Sea, the Pearl River was not previously paid attention to from the viewpoint of clay mineralogy. This paper presents a detailed study on clay minerals in surface sediments collected from the Pearl River drainage basin （including all three main channels, various branches, and the Lingdingyang in the estuary） by using the X-ray diffraction （XRD） method. The results indicate that the clay mineral assemblage consists dominantly of kaolinite （35%-65%）, lesser abundance of chlorite （20%-35%） and illite （12%-42%）, and very scare smectite occurrences （generally 〈5%）. Their respective distribution does not present any obvious difference throughout the Pearl River drainage basin. However, downstream the Pearl River to the northern South China Sea, the clay mineral assemblage varies significantly： kaolinite decreases gradually, smecUte and illite increase gradually. Additionally, illite chemistry index steps down and illite crystallinity steps up. These variations indicate the contribution of major kaolinite, lesser illite and chlorite, and very scarce smecUte to the northern South China Sea from the Pearl River drainage basin. The maximum contribution of clay minerals from the Pearl River is 72% to the northern margin and only 15% to the northern slope of the South China Sea. In both glacials and interglacials, kaolinite indicates that the ability of mechanical erosion occurred in the Pearl River drainage basin.
