摘要
崂山的地貌景观十分复杂 ,形成众多的奇山异石。研究发现 :更新世期间 ,崂山发生过多次古冰川作用 ,从水下到山巅都留下古冰川活动的印记。崂山的冰碛物具有不成层、无分选、杂乱无章、大小不一、由带有磨光面的、个体差别很大的和带有棱角的岩块、砂等堆积而成 ,部分冰碛物伸入海下。崂山古冰川冰碛物的堆积地貌主要有终碛堤、冰碛丘陵和侧碛堤三种类型。崂山古冰川侵蚀地貌有 :(1)拖蚀 (拔蚀 )岩块 ;(2)磨光面 ;(3)古冰斗 ;(4)“刃脊”、角峰、哑口 ;(5)削断山嘴“U”型谷 ;(6)冰臼。崂山低海拔古冰川遗迹的发现 ,对研究崂山地貌演化和第四纪黄渤海陆架环境变迁 ,具有十分重要意义。
Many times of palaeo-glacier activities had happened in mountain.Laoshan during Pleistocene,and left imprints of palaeo-glacier from mountaintop to the foot of mountain.Laoshan.There are some records that related to reˉmains of palaeo-glacier in the book of'Record of mountain.Laoshan'.Three types of accumulated geomorphies of palaeo-glacier are founded in mountain.Laoshan as following:end-moraine mound,moraine hills and lateral moraine mound.Many erosion geomorphies of palaeo-glacier as dragged(drawn)rocks,polished face,palaeo-cirques,'knife-edges',angle ridges,mouth-type geomorphies s,cut counterfort,‘U'typical-riverbed,ice mortar etc are discovered in mountain Laoshan.
