摘要
大别山榴辉岩带中浅变质火山—碎屑岩层组合及其震旦纪孢粉组合的发现，为确定大别山表壳岩的时代，及其与邻区地层对比提供了重要依据。对区内主要沉积特征识别，确立大别山浊积岩与浊流沉积序列及大地构造背景，正确认识该造山带的形成环境、构造演化具有重要意义。
The features of epimetamorphic volcanic clastic rock bed association and its sporopollen assoliation of the Sinian in eclogites provide a basis of importance for determing the time for surfacial crust rocks in the Dabie Mt. and their correlation with the neighbouring area of strata. The determined turbidite,turbidty current deposit sequences and tectonic environments through diagnosis of the main deposit features in the area are gelogically significant to correctly recognizing the formation of environment and structural evolution of the orogen.
