摘　　要：位于华北陆块与扬子陆块之间的桐柏-大别山系是我国划分东部南北两大地质构造分区的重要结合带。湖北北部蓝片岩带展布于桐柏-大别造山带南部,通过对桐柏山南缘的余店蓝片岩带和木兰山蓝片岩带的分布特征、岩石类型及岩石矿物学特征的论述,总结分析了鄂北蓝片岩带的变质特征及变形特征。The Tongbai-Dabie Mountains located between the North China block and the Yangtze block is an important juncture. The blueschist belt in north Hubei is exposed in the south of the Tongbai-Dabie orogenic belt. This paper deals with distribution, rock type and petrological characteristics blue schist belt in Yudian and Mulanshan on the southern margin of the Tongbai Mountains and metamorphic and deformation characteristics blueschist belt in north Hubei.
