| 摘 要： | 通过对福建省典型崩岗发育区的实地调查和局部钻探研究,探讨了深厚风化壳形成的地质成因.结果表明:构造活动历史是崩岗区形成深厚风化壳的主导因素;构造活动影响崩岗侵蚀动力势能以及各断块遭受侵蚀的历史;侵蚀动力势能和侵蚀历史确定了崩岗发育之前风化壳的厚度.当构造运动条件适合时,岩石的构造节理不发育的区域也可以形成深厚风化壳.

| Abstract: | Through field surveying and drilling in Benggang erosion area of Fujian Province,the geological factors of weathering mantle formation were discussed.The result showed that tectonic movement history was a key factor in the deep weathering mantle formation.Tectonic movement influenced driving force and potential energy of Benggangs,and eroded history of each cracking block,which determined the depth of weathering mantle.The deep weathering mantle could form when tectonic movement was under proper condition,e... |
