Mapping and sedimentological and stratigraphic characterisation of outcrop sections using facies analysis, combined with conodont and foraminiferal biostratigraphy, has led to identification of two major phases of Pha Nok Khao Platform development: (1) Bashkirian-Moscovian mixed siliciclastic-carbonate ramps with beresellid algal mounds, coral-chaetetid mounds and grainstone shoals; and (2) a broad Moscovian-earliest Permian platform with locally steepened margins and coarse slope facies. Calcisponge-algal- Tubiphytes-Archaeolithoporella boundstone formed mounds on the upper slope, locally represented by allochthonous blocks, with phylloid algal mounds on the inner platform. Improved understanding of reefal buildups and shoals is important for understanding Permian petroleum reservoirs worldwide.
