根据对华南地区二叠系栖霞组内菊花石假象的成因研究 ,结合对该组内燧石结核、菊花石内正延性玉髓和海泡石形成时代关系的观察 ,认为华南地区栖霞组内的海泡石形成于早期成岩作用过程中 ,与该组内燧石结核和菊花石假象内的正延性玉髓同期形成。其成因既与高盐度的沉积环境或高盐度的成岩环境条件无关 ,也与热液活动无关。 According to the research on the causes of the chrysanthemum in the Permian Qixia Formation in South China, combined with the observation of the formation age of the chevron, chrysanthemum, orthodontic chalcedony and sepiolite in this group, it is considered that the sea in the Qixia Formation in South China Confirm stone formation in the early diagenesis process, and the group within the flintstone and chrysanthemum stone within the ductile chalcedony within the same period of formation. Its cause is not related to the high salinity sedimentary environment or high salinity diagenetic environmental conditions, but also has nothing to do with the hydrothermal activity.
