| 摘 要： | 笔者于1986年在钟祥首次发现了第四纪地层间的冰缘融冻构造——古冰楔与揉皱,其时代为早更新世末期—中更新世初期。它的发现不仅为建立本区第四纪地层层序,而且为确定更新世北方冰缘冻土的南界和研究长江中下游更新世古气候环境的演变提供了重要的科学依据。

| Abstract: | The frost riving structure in the Quaternary interlayer-fossil ice-wedges and wrinkles were discovered in Zhongxiang in 1986, they were all located on the northern edge of the Jianghan Plain, and were formed during the period from late Early Pleistocene to early Middle Pleis. This discovery may be useful not only for the setting up of the stratigraphic sequence of Quaternary in this district, but also for it can provide important evidence for the identification of the southern boundary of the Northern ice-front climafrost, and also for the studing of the evolution of paleoclimate and environment between the middle reach and lower reach of Yangtze River at that time. |
