Xisha event cycle, representing event records from late Pliocene to early early Pleistocene, are determined through stratigraphic records, dolomitized horizons and characteristics, oxygen isotope values and geochemical parameters in the studies of longitudinal sequences of Xisha organic reefs. The cycle is made up of 3 stages, i. e., the early, middle (principal) and late cycle stages, with a total time span between 180 to 315 Ma.

At presen, he astronomical factors, crustal movements and the superimposition of the feedback process provide the most perfect interpretation for the arrival of the clima e of ice age. The relationship between the frequency of continental ice flow and cycles of ice age indicated by the deposition of deep sea is also discussed in the article.
