摘要
本文在广西海岸带调查资料的基础上进行综合分析,论述了广西沿岸浅海水下三角洲、水下岸坡、古滨海平原和海底平原等水下地貌的形态特征及其展布规模,通过对各种地貌类型中的沉积物组成进行研究,阐述了沉积物的粒度、碎屑重矿物、微体古生物在各种地貌部位上的分布特征。
Based on the synthetic analyses of the investigation data along the coastal zone of Guangxi Province, the geomorphological and distributional characteristics of underwater delta,coastal slope,ancient offshore plain,and submarine plain were discussed. The sedimentary grain size, clastic heavy minerals and micropaleontological distribution in the different geo morphological settings were analyzed by the study of sedimentary compositions in varied geomorphological types in this paper.
