| 描述 珊瑚化石，俗稱石柱子、珊瑚玉，是由於單體珊瑚的外層細胞，具有分泌石灰質外骨骼能力，石灰質包裹住軟體部分，形成了珊瑚的外壁。常見的珊瑚化石有單體和復體兩大類型。 珊瑚化石有單體和複體兩大類型。單體珊瑚的骸體，從幾亳米到幾十亳米，通常有體壁圍繞，表面飾有粗細不等的皺紋。複體珊瑚呈致密的塊狀體，由許多細小的珊瑚個體組成。珊瑚骸體的骨架由無數細微的，方解石質或文石質的羽針、羽簇或羽榍組成。 | Descriptions Coral fossils, commonly known as stone pillars and coral jade, are due to the outer cells of the monolithic corals, which have the ability to secrete calcareous exoskeletons. The limestone envelops the soft parts and forms the outer walls of the corals. Common coral fossils come in two types, monomer and complex. Coral Fossil is a natural type of gemstone formed by ancient corals. The proper name for fossil coral is ‘agatized coral’ or ‘agatized fossil coral’. Because during formation, the coral remains are gradually replaced with agate, a variety of naturally occuring chalcedony, or microcrystalline quartz. |
