A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.
综合岩相观察结果，建构一个符合台湾西南部更新世珊瑚礁与基底泥岩接触关系的沉积相模式；其中，基底泥岩顶部的不规则冲蚀面、充填碳酸盐胶结泥岩砾与碳酸岩烟柱的漏斗状沉积，以及块状冷泉碳酸盐岩的出露，可能均为区域地质构造活动时期所造成；至於与含化石泥岩同时沉积的砾岩相，可能均为基底泥岩在快速浅化的过程中所沉积，标志古环境由矽质碎屑快速转变为碳酸盐环境的过程。

Sedimentary facies model for mixed sediments of recent reefoid carbonates and siliciclastics is developed from the facies model of fringing and barrier reefs. Based on the sedimentary facies and textures, mixed sediments may be subdivided into 5 types as follows: 1 reef base mixed sedimentary rocks and reef framework mixed sedimentary rocks; 2 reef flat sand-gravel mixed sedimentary rocks; 3 backreef beach-dune gravel-sand mixed sediments; 4 backreef lagoonal sand mixed sediments ; and 5 reef front littoral sand mixed sediments.
