前言本文据实地调查结果,将冲绳本岛内湾域的浅海碳酸盐作为一个物源,就冲绳海槽至琉球海沟斜坡范围内浅海碳酸盐的分布问题试作评述。浅海碳酸盐的砂质沉积物沿着斜坡朝深海搬运,由于斜坡向海底延伸、水深逐渐增大,
Preface This paper presents an assessment of the distribution of shallow-sea carbonates within the Okinawa Trough to Ryukyu Trench slope, using the shallow-sea carbonate in the Gulf of Okinawa as a source, based on field findings. Sandy sediments of shallow-sea carbonate are transported along the slopes toward the deep sea. Due to the slope extending to the sea floor, the water depth gradually increases,
