4. In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod, sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascendingorder: 20～120 m, 80～130 m, about 150 m, 50～250 m, and in excess of 200 m.
根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义，认为五峰组底部灰绿色泥岩段产出时水深约60-100m，观音桥层水深约50-80m，在晚奥陶世最大海侵期(对应于T.typicus亚带下部)，水深约400m，五峰组含放射虫硅质岩沉积时最小水深约200m，结合以上海平面变化的5次旋回，从而推算出各旋回海平面的变化幅度：在第①旋回，海平面变化范围大致为20～120m；在第②、第③和第④旋回中，海平面变化分别为80～130 m、大约150 m和50～250m；第⑤旋回的海平面升降幅度大于200 m。
