木化石林

木化石，学名硅化木，是上古时代树木被地壳运动、火山爆发所掩埋，在特定的地质环境下（如高温、高压、高硅水），木质部分逐渐被水中的二氧化硅置换填充，最终形成的保留树木原有形状的石化物。其地质年代大约在2亿年前后。

The fossil wood has the scientific name of silicified wood. In ancient times, trees were buried due to crustal movement and volcanic eruption. Under the specific geological environment (such as high temperature, high pressure and high silicon water), the wooden parts were gradually replaced by silicon dioxide in water and finally became the petrified wood which retained the original shape of trees. It dated back to about 200 million years ago.
