摘　　要：本文对怀涿盆地中发现的冻融褶皱现象的典型剖面进行详细观察和描述，并对其沉积物做了孢粉分析，初步认为：发生冻融褶皱时期的孢粉组合及其古植被所指示的古气候环境为一寒冷的冰期气候条件下的冷湿环境。据Ｃ（１４）测定其年代为晚更新世晚期。hrough detailed observation and deicription of the typical section of the involutionfound in the Huailai-Zhuolu Basin and analysis of the Spore-Pollen, the author premarily believes the Palaeovegetation of deposition date of the involution belongs to an ice-climate of the coldand wet environment. Measured with C14, the age is late pleistocent, that is, 11030±150 or 109701300 years.
