There are many depositional characteristics of storm deposits in the Lower Sinian Jiayunn Formation around Xuzhou area, including scouringfilling structures, hummocky crossstratifications, storm flowgenerated intraclastic limestones, graded bedding and convolute bedding. Through detailed field observation and laboratory study, a total of six types of storm deposits have been recognized.Type I is represented by the thin bedded silty micrites formed by distal stormturbidity currents below storm wave base. Type II is characterized by the limestones with gutter cast and HCS, which were deposited at the place between storm and fine weather wave base. Type III consists of intraclastic limestones with the debris flow introclasts, HCS, and scouring base, which was formed in the vicinity of the fair weather wave base. Type IV is characterized by the intraclastic limestones with scouring surface, HCS and convolute bedding, which was formed in the upper ramp environment. Type V is characterized by oolitic rudaceous limestones intercalated within the lagoonfacies thinbedded limestones, which wasdeposited at shoal side of the lagoon. Type VI is represented by lagoonfaciesstorm deposits with scouring surface, thinbedded intraclastic limestones, HCSand fair weather deposits. These types of storm deposits tend to superimpose each other vertically to form an upward shallowing sequence.
