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。

Ma,and lithosphere delamination and thermal exhumation during 196～163?Ma.The rapid thermal exhumation,co\|occurred with extensive regional metamorphism and intermediate\|acidic magmatism,implied that the subducted slabs had broken off and delaminated.The p T t path of UHPM consists of two curves,i.e.,a barrette\|like curve reflecting the process of cold slab subduction and exhumation,and a crescent curve representing the thermal exhumation after slab breakoff.

通过全面评述该区变质岩研究成果，作者认为：超高压变质岩的形成和剥露经历了240～200 Ma的板片冷俯冲冷折返和196～163 Ma的岩石圈拆沉热折返；热折返伴随了广泛而强烈的区域变质作用和中酸性岩浆活动，指示板片断离拆沉的发生；超高压变质岩p-T-t轨迹由两部分组成，即反映板片冷俯冲冷折返过程的发夹状曲线和指示板片断离拆沉热折返过程的新月形曲线。

The main body of the outcropping rock layer is composed of deep gray trachyte of Baitoushan formation of mid-Pleistocene series and yellow, brown yellow volcanic-tuff crust of weather. This kind of structure that weak layers and hard layers emerge alternately contributes to the instability of rock mass.

长白山一带出露的地层主体为中更新统白头山组深灰色粗面岩及黄色、褐黄色火山凝灰岩、火山灰风化壳，这种软硬相间的层状地层组合为岩体的失稳创造了条件，岩体失稳产生的堆积物为泥石流准备了充足的固体物质。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
