摘　　要：根据冲绳海槽表层沉积物的重矿物含量变化、物源、成因、地貌和沉积特征划分出东海陆坡、琉球岛坡和海槽槽底三个矿物组合区以及六个矿物组合亚区，并对其物质来源和影响范围作了讨论。On the basis of the component variatoin, source and origin of minerals, geomorgraph and sedimentary characteristics. The Middle Okinawa Trough can be divided into the East China Sea Continental Slope Mineral Province, Ryukyu Islands Slope Mineral Province and the Middle Okinawa Trough Bottom Mineral Province,and six Mineral Subprovinces. Their sources and dispersal are discussed.
