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。

By sutdy and gathering information, some important conclusions are presented:(1) Ruby deposits of marble type were located in the plutonic metamorphic zones of orogene where deep-seated fault structure is developed;(2) Genesis of the deposit belongs to the type of thermal-dynamic metamorphism;(3) Ruby-bearing rocks are calcic crystalline marbles, not magnesian marbles;(4) Amphiboles in ruby-bearing rocks arenot tremolites, but silica-poor alumina-rich and chrome-bearing calcic amphiboles.

目前，对于此类型矿床找矿相关的若干重要问题的认识，还相当模糊，主要表现在以下几方面：（1）对此类型矿床的产出构造背景认识不清；（2）认为此类矿床的成因类型为&气成一热液型&或&矽卡岩型&；（3）认为含矿岩石为镁质大理岩或镁质矽卡岩；（4）认为含矿岩石中的角门石为透门石。本文通过实际研究①和相关文献资料的搜集整理，分别对这些

The exposed massive cold-seep carbonates provided substrate for the encrustations of corals as well as coralline algae and might have played a crucial role in the initial development of coral reefs in a siliciclastic paleoenvironment of active tectonic setting. This is probable the first case of the world that cold-seep carbonates acting as initial colonization hardgrounds of hermatypic corals and corallines.

在此基底泥岩快速浅化的过程中，出露的块状冷泉碳酸盐岩成为不稳定地体构造背景中，珊瑚与珊瑚藻等表覆生物在矽质碎屑环境生长的硬底质，可能在礁体的最初发育扮演关键性的角色；此种冷泉碳酸盐岩成为造礁珊瑚与珊瑚藻在矽质碎屑古环境中最初生长硬底质的现象，很可能为世界首例。
