Abstract
A comprehensive review of Middle and Upper Devonian reefs, based on about 350 papers describing the reef development within 44 areas all over the world, resulted in the recognition of four reef megacycles (Upper Eifelian; Givetian; Uppermost Givetian to Frasnian; Upper Frasnian to Lower Famennian). These megacycles are characterized by the occurrence of typical reef types and by characteristic microfacies associations. Twelve microfacies associations can be distinguished using lithological, paleontological and microfacies criteria; each microfacies association includes several standard microfacies types.
