摘　　要：通过对武当山推覆体东南缘耀岭河群沉积特征和微古植物组合面貌的初探，认为耀岭河群属沉积火山碎屑岩类型并兼有冰筏－海相火山沉积特点，结合冰成岩时限、微古化石及同位素年龄数据等，将研究区耀岭河群的地层时代确定为震旦纪。A primary research on the sedimentary characters and micropaleontologic assemblages of Yaolinghe Group in the southeast border of the Wudang Mountains nappe shows that Yaolinghe Group belongs to sedimentary pyroclastic rock type and has the properties of ice rafting-marine volcanic sedimentary,The stratigraphic time of Yaolinghe Group is establised as Sinian period according to the time range of glacigenous rocks, micropaleontologic fossils and isotopic age.
