海南岛西北岸礁坪堆积物的粒度参数与分布特征

松散堆积物的粒度成分及分布规律与沉积环境息息相关,于潮间带以平台地形出现的现代礁坪对其上的松散堆积物的沉积过程施于深刻的影响.本文就海南岛西北岸邻昌、大铲离岸礁和小铲近岸滩礁礁坪上的松散堆积物的粒度参数和粒度分布的若干特征,探讨它们与沉积环境的关系.

THE ACCUMULATIONAL MATERIALS ON THE REEF FLATS ALONG THE NORTHWESTERN BANK OF HAINAN ISLAND:FEATURES OF THEIR GRAIN SIZE PARAMETER AND DISTRIBUTION

The grain size elements of the loose accumulational materials and their distribution are closely related to the sedimentary environment. The sedimentary process of the loose accumulational materials is strongly affected by the modern reef flat which assumes the form of a platform in the intertidal zone. This paper discusses the features of the grain size parameter and distribution of the loose accumulational materials on the reef flats of the barrier reef and the nearshore bank reef along the northwestern bank of Hai Nan Island and their relation to the sedimentary environment.
