Abstract
New exposures in the Upper Permian to basal Triassic carbonate succession near
Shanggan (Leye County, NW Guangxi, South China) shows an Upper Permian stromatactis
mound directly resting on top of a coral reef. The top of this Late Permian stromatactis
buildup is cut by an irregular surface overlain by a 1.5 m thick high-energy laminated lime
grainstone followed by a 5 m thick basal Triassic stromatolite facies. The upper, domal part of
this microbial buildup displays centimetric cavities of stromatactis type cemented by blocky
calcite.
