| 地質年代：二疊紀時代

Geological Age: Permian age
|
| 形成：石灰岩由化學物質—碳酸鈣和碳酸鎂組成。它由小型生物或植物的骨架（有機石灰石）沉積而成，或者通過化學沉澱，或者通過在海床和湖泊床上沉積石灰石碎片而形成。
|
Formation: Limestone is made up of the following chemicals with calcium and magnesium carbonate. It is formed by the deposition either of the skeletons of small creatures and/or plants (organic limestones), or by chemical precipitation, or by deposition of fragments of limestone rock, on the beds of seas and lakes.
|
| 特性：大多數石灰石的顏色是不同的灰色和棕褐色。灰色是由含碳雜質的存在引起，而鐵是由於存在鐵而引起的。已經發現，所有石灰石都是結晶的，但具有不同的晶體尺寸，單位形狀和晶體排列。用於石材，密度和硬度有相應的變化。
|
Properties: The colour of most limestones is varying shades of grey and tan. The grey colour is caused by the presence of carbonaceous impurities-and the tan by the presence of iron. It has been found that all limestones are crystalline but with varying crystal sizes, unit formity, and crystal arrangement. This ret suits in stone with a corresponding variance in density and hardness.
|
| 用途：石灰岩用於混凝土骨料、鋪路基石、水泥、冶金熔劑、水處理、土壤調節劑、家禽飼料添加劑，及輕工、化工、紡織、食品等。
|
Application: Limestone is used for concrete aggregates, paving stones, cements, metallurgical fluxes, water treatment, soil conditioners, poultry feed additives, and light industry, chemicals, textiles, and foodstuffs.
|
| 分佈：台灣石灰岩的分佈是海岸隆起之珊瑚礁，主要分布於西南部海岸。
|
Distribution: The distribution of limestone in Taiwan is a reef that rises along the coast and is mainly distributed on the southwestern coast.
