Wu Weijiang, Ye Weilin, Meng Xingmin, Wang Zongli. The Definition of the Ancient Landslide Age with the
14C Dating of Hanlingou River Basin in Wudu[J]. Advances in Earth Science, 2011, 26(12): 1276-1281.
The ancient landslides were usually formed in the period of earth evolvement before Holocene. Landslides of Hanlingou River Basin grew well in the different periods during the Epipleistocene and their characteristics present as being on a large scale and in large quantity. It gives several typical examples to study the development of landslides of the middle reach of the Bailongjiang River in Wudu. The ancient landslides grew well by analysis of the topography and characteristics of structure of landslide and contact relations of strata. The research results also show that the water resources from Hanlingou was cut off to form barrier lakes by earthquake and many old trees were buried. Now, a large number of the remains of plants remain in the landslides. According to the 14C dating from the root of a tree, the ancient landslides grew about 42.0~44.8 ka BP.
