| 地質年代：(化石) (岩石)
化學組成, 鍵及結構：(礦物) 主要由蛇纹石矿物组成 |
Geological Age: (Fossil) (Rock)
Chemical composition, bonding and structure: (Mineral) serpentinite rock, partially made up of chrysotile |
| 形成：(岩石) (礦物) 由富镁之硅酸盐矿物经热水蚀变或变质作用，将超基性 岩石中的橄榄石和辉石与水作用发生蛇纹石化，从而形成的一种变质岩石。
原生物：(化石) |
Formation:(Rock) (Mineral) formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth’s mantle.
Living Specimens: (Fossil) |
| 特性：
蛇纹岩质软，具有滑感，主要由蛇纹石组成，颜色一般为灰绿色、黑绿色或黄绿色，色泽不均匀，颜色鲜艳半透明 |
Properties:
Soil cover over serpentinite bedrock tends to be thin or absent. Soil with serpentine is poor in calcium and other major plant nutrients, but rich in elements toxic to plants such as chromium and nickel.
|
| 用途：(岩石) (礦物)
可以作为工艺品原料或建筑装饰材料，蛇纹岩石棉可以作为耐火材料，可以作为提炼镁或钙磷镁肥的原料，伴生的矿物有磁铁矿、钛铁矿、铬铁矿、菱镁矿、滑石、石棉、镍、钴、铂等。 |
Application: (Rock) (Mineral)
Serpentinite has a significant amount of bound water, hence it contains abundant hydrogen atoms able to slow down neutrons by elastic collision. Because of this serpentinite can be used a s dry filler inside steel jackets in some designs of nuclear reactors.

| 分佈：(岩石) (礦物)
台湾蛇纹岩，主要分布在南澳、丰田、万荣、瑞穗、玉里、关山与台东地区。中国蛇纹岩主要分布在内蒙、甘肃、云南、四川、西藏等地。 |
Distribution: (Rock) (Mineral)
The shallow soils and sparse vegetation lead to elevated soil temperatures, dry conditions. |
