摘　　要：全面总结分析了有关武当地块耀岭河群火山岩年代学及相关问题等前人研究成果,结合本文研究成果展开了深入讨论。得出:①耀岭河群火山岩属大陆拉斑玄武岩—碱性玄武系列;②耀岭河群基性火山岩与地幔柱源岩浆起源的火山岩具有相似性;③耀岭河群火山岩年龄为(632 1)M a左右较为可信等重要结论。There are many disputes on research of Yaolinghe group volcanic rocks in the Wudang Block, but the points focus on its chronology and relevant issues, in the paper, the achievements of past scholars are analyzed to further discuss the controversial subjects with author＇ s own studies. Finally the results of volcanic rocks of Yaolinghe group conclude as follows：（1） it belongs to the series of alkali-basalts and some tholeiites;（2） it is quite similar with mantle plume source volcanic rocks ; （3） it＇ s more reliable that the rocks have formed since （632 -＋ 1 ） Ma approximately.
