照片 1中这只小绵羊 (见封三 ) ,很像当年育成的小肥羊 ,但它是一块戈壁石 ,长 1 8cm、高 1 2 cm,硬度达到摩氏 7度。为火山期后硅质热液渗入玄武岩气孔中冷凝而成 ,是天然铸就的绵羊雕像。当玄武岩被风化以后 ,又残留原地 ,经戈壁风砂千百年的研磨侵蚀 ,尤如被涂上一层黄色沙 Photo 1, this little sheep (see cover three), much like the young sheep bred then, but it is a Gobi stone, length 18cm, height 12cm, hardness of 7 degrees Mohs.
