摘要:
多年来,随着对中国海沉积物的调查研究,笔者对黄海、渤海、东海、南海北部陆架区与北部湾沉积物中的碎屑矿物组合及其分布模式进行了研究。调查范围如图1所示,其跨度为东经106°—129°,北纬17°—41°。作者共分析了760个海底表层沉积物样品,并对黄河、长江、辽河、滦河、六股河等河流沉积物的样品进行了分析,分析样品数为47个。
Abstract:
We have made studies on the detrital mineral components and their distribution patterns in the sediments of the Bohai Sea, the Huanghai Sea(Yellow Sea)，the East China Sea, the northern continental shelf of the South China Sea, and Gulf of Tonkin. The results show that the sediments are made up of 59 mineral components. The light minerals(less than 2.8 in specific gravity)are mainly quartz and feld- spar. The heavy minerals such as hornblende, epidote, schistose minerals,(muscovite +chlorite+biotite)and ilmenite preponderate in number. The garnet, zircon, dolo- mite, pyroaene and tourmaline come second. The contents of other minerals are very low. The distribution patterns of these minerals are described as follows.
