一、前言在稻科草本和樟科木本等植物中,土壤中的硅酸(SiO_2)可以依附在其细胞内壁上,随着积蓄的硅酸量逐渐增加,会形成植物细胞形状的被称为植物硅酸体(silica body)的物质。植物体死亡、分解后,植物硅酸体保留下来,这就是植物蛋白石(plant opal)。植物蛋白石由于其自身的化学特性和物理风化的作用变得非常坚硬,如果再加上合适的保存环境这些蛋白石就会半永久性地保存下来。由于不同植物的细胞形状各异, I. Introduction In the plants of the genus Mycenae and camphor wood, the silicic acid (SiO 2) in the soil can attach to the inner walls of the cells. As the amount of accumulated silicic acid gradually increases, the shape of plant cells is called It is a substance of plant silica body. Plant death, decomposition of plant silicate retained, this is the plant opal (plant opal). Plant opal is very hard due to its own chemical properties and physical weathering, and these opals are preserved semi-permanently if combined with a suitable preservation environment. Due to the different cell shapes of different plants,
