Abstract: According to structure features, the Changxing reefs are classified as mature, semimature and imma-ture reefs. The mature reefs have the characteristics of large scale, complex shape, complete structure, lots of hermatrypic organisms and shallowing sedimentary sequence. The immature reefs have the char-acteristics of small scale, simple shape, incomplete structure, a few hermatrypic organisms and deepening sedimentary sequence. The semimature reefs'characteristics are between the mature reefs and the imma-ture reefs. The mature reefs are distributed over platform edge and transition of platform-flat and plat-form-mulde deep water. The semimature reefs are distributed over transition of platform-flat and plat-form-mulde semideep water. The immaturereefs are distributed over platform-flat and platform-mulde.
