There is no record of the pre-Quaternary ancient rocky shore in China. The exception is an Early Silurian (latest Middle Llandovery) karst shore known to be well exposed at Huanghuachong, 2. 6 km south from Wudang Village, about 13 km northeast of Guiyang, Central Guizhou, SW China. At Huanghuachong, the Lower Silurian Gaozhaitian Formation oversteps 63 m of palaeotopographical relief in argillaceous limestones of the Llanvirn Kuniutan Formation and crystalline limestones belonging to the Caradoc to early Ashgill Huanghuachong Formation. It indicates that a transgressive event took place during the late Aeronian (sedgwickii Biozone, Middle Llandovery) time in central Guizhou with the local sea level rising 63 m. The change of sea level also fits well with a global rise of sea level in epicontinental waters on several different palaeocontinents in the late Aeronian. However, by no means does this result imply that the coast was 63 m deep during the maximum peak of the Aeronian transgression. Indeed, the opposite was true, because the area was rapidly dilled with fine elastics derived from the erosion of the exposed late Arenig Meitan Formation. Borings of the ichnofossil Trypanites are reported from the karst unconformity at the top of the Huanghuachong Formation, confirming a littoral to very shallow submarine incursion against the karst coastline. No encrusting fauna has been encountered, probably because on the Huanghuachong karst surface there would have been turbidity current deposits of the Silurian transgression which would have been eroded away, or in any case, the actual unconformity surface is very limited in the area searched. A palaeogeographical map covering northern and central Guizhou Province has been constructed in terms of the Silurian karst shoreline near Wudang.
