中国海及其邻近海域的粘土矿物

本文对中国海及其邻近海域的354个站的表层沉积物中的粘土矿物,进行了系统的定性和半定量分析。对所得资料进行了数学处理,求得4种主要粘士矿物的趋势分布图和中国海及其邻近海域的4个主要不同物源的沉积区,建立了中国海及其邻近海域细粒物质的运移扩散模式。     

CLAY MINERALS IN THE CHINA SEA AND ADJACENT SEAS

The clay minerals in the surface sediments from 354 stations have been analyzed qualita-tively and semiquantitatively. The obtained data are dealt mathematically. According to thecalculated results, the distribution laws and the trends of content changes of clay mineralsare discussed. The studied area is divided into four main provinces of sediments with differ-ent sources. Finally the author approached the laws of the migration and dispersal of thefine-grained matter carried into the seas by the Huanghe River, the Changjiang River, theZhujiang River and the Philippine Archipelagoes, and set up the transport model of the fine-grained matter in the China Sea and adjacent seas.
