摘要

臺灣的蛇紋石係海洋地殼中的基性或超基性岩石，經構造作用或變質作用而形成，其屬於變質超基性岩石。蛇紋石原料石礦皆以露天階段方式開採，蛇紋石石材礦皆以露天階段方式布設採掘面，而後以鑽孔劈楔法或金鋼索鋸法或鏈鋸法開採。蛇紋石主要供作建材、煉鋼助熔劑、工藝品、農業肥料及環保使用。

並列摘要

Taiwan's serpentine is originally formed from basic or ultrabasic rocks within the oceanic crust. These rocks are formed by metamorphism or displacement of geologic processes. They are categorized as metamorphic ultrabasic rocks. All raw material mines are open-pit mines using the bench-cut method. Dimension stone mines are open-pit mines using the bench-cut method, then extracted by drilling splitting method, diamond wire saws or chain saws. Serpentine is normally used for making building materials, fluxes for steel making, artifacts, agricultural fertilizers and environmental engineering.
