The Late Carboniferous phylloid aglal reef occurs in the carbonate platform margin. In this paper the phylloid reef’s microfacies characteristic and sedimentary environment are analyzed by the way of detailed section microfacies analysis. The authors summed up 6 carbonate microfacies, i.e. bioclastic wackstone, bioclastic packstone, pelleted bioclastic packstone, phylloid algal wackstone and packstone, brachiopod packstone, and bioclastic grainstone. The authors summed up a part sedimentary facies model, transfers from the depth open carbonate platform facies, phylloid algal reef facies, inner carbonate platform slope facies, inner carbonate platform shallow slope facies, shallow open carbonate platform facies, to intraplatform shoal facies, analyzing sedimentary environment of phylloid aglal reef. Based on the distribution of microfacies in the section, the authors can speculate it is the open carbonate platform environment in subtidal zone.
