摘要
通过对双阳盆地小蜂蜜顶子组同位素年令岩样测定结果和其所含植物化石的讨论，认为该组的地质时代应归属于中侏罗世晚期，并可与辽源地区的夏家街组对比。
Based on the measuring results of istope age of Xiaofengmidingzi Formation in Shuangyang Basin and its plant fossile,the geological Xage of the formation is in later period of Middel Jurassic and can compare with Xiajiajie Formation.
