Abstract

On the basis of discussing the paleogeographic reconstruction,the change of lithology and biota through t he section，the cycles of Ce anormaly and the indicating biota for depth of water mass fromt he latest Ordovician in the Yangtze Basin，the author holds that 5 eustatic cycles in the latest Ordovician Wufengian and that,the depth of water mass is at least 50 to 80 metres(respect to Guanyinqiao Bed)and at most 500 metres or so.
- paleogeographic reconstruction,
- lithology and biota,
- Ce anormaly,
- eustatic cycles,
- Wufengian Yangtse Basin,
