树化石又称硅化木,是地质历史时期的树木经历地质变迁,埋藏在地层中经历地下水的化学交换、填充作用,其化学物质结晶沉积在树木的木质部分,将树木的原始结构保留下来而形成的木化石。硅化木主要生成于中生代时期,以侏罗纪,白垩纪最多。树化石的成因树化石是几百万年或更早以前的扣叶木被迅速埋葬地下后,木质部分被地下水中的二氧化砖交换而成的树木化石。它保留了树木的木质结构和纹理,颜色为:土黄、淡黄、黄褐、红褐、灰白、灰黑等,抛光面可具玻璃光泽,不透明或微透明。因部分术化石的质地呈现玉石质感,又称为树化 Tree fossils, also known as silicified wood, are geological changes during the geological history of the trees, buried in the strata undergoing chemical exchange of groundwater, fill the role of the chemical crystal deposition in the woody part of the tree, the original structure of the tree retained the formation of Wood fossils. Silicified wood was mainly generated in the Mesozoic period, Jurassic, Cretaceous up. Tree fossils cause tree fossils are millions of years ago or earlier buckle leaves were quickly buried underground, the woody part of the groundwater from the brick in the exchange of the tree fossils. It retains the wood structure and texture of trees, colors are: yellow, yellow, yellow brown, reddish brown, gray, gray and black, polished surface can be shiny glass, opaque or slightly transparent. Due to the fossil texture of some jade texture, also known as tree
