说起石林,一定让你激动不已,而谈到土林,你也许就困惑了吧,土还能成林?能!同在云南,那因发现了170万年前的元谋猿人而遐迩闻名的元谋县,就有一片面积达50多平方公里的土林,它雄险奇秀,伟岸而幽深,令无数游人叹为观止。元谋土林主要发育在新生界第四系早更新统元谋组地层中。该地层岩层倾斜缓,有利于岩柱保持稳定。这一地层有丰富的动植物化石和膨胀土成分,雨后泡水体积膨胀,旱季脱水体积缩小,致使地面龟裂;在数十万年乃至百万年的雨水冲刷及地壳运动抬升等作用
Speaking of Stone Forest, we must make you excited, and talked about the forest, you may be confused right, the soil can become a forest? Can! In Yunnan, then found 170 million years ago Yuanmou ape and far better known Yuanmou County, there is an area of more than 50 square kilometers of forest soil, it Xiongqi Qi Xiu, stalwart and deep, so many visitors amazing. Yuanmou soil forest is mainly developed in the Cenozoic Quaternary Early Pleistocene Yuanmou formation. The strata of the strata are gently inclined to be conducive to the stability of the pillars. This formation is rich in animal and plant fossils and expansive soil components, after the rain bubble water volume expansion, dehydration volume shrinking during the dry season, resulting in ground cracking; hundreds of thousands of years and millions of years of erosion and crustal movement uplift role
