图10 海底扇水道单元模式[54] (a) 欠充填水道单元，发育加积天然堤，半合并化的不同岩相，泥质/粉砂质盖层，向上变细的废弃相；(b)充填水道单元，发育欠加积天然堤/漫滩沉积，合并化的相似岩相，缺少泥质/粉砂质盖层和废弃相

Fig.10 Schematic representations of common fill styles of under-filled and filled channel elements[54] (a) Under-filled channel element with moderate to high rate of overbank aggradation, semi-amalgamated highly heterolithic fill,common shale/silt drapes, and capped by upward fining abandonment-fill facies； (b) Filled channel element with low rate of overbank aggradation, amalgamated and less heterolithic fill, and rare shale/silt drapes
