摘要
河北平泉中元古界长城群高于在组地层中发育风暴浊积岩。在沉积序列、结构构造、矿物成分及显微组构的研究基础上，采用分数维函数理论研究了该区风暴浊积岩的形成规律，发现地质历史上的风暴作用强度与其频率之间存在着一种分数维函数关系，显示了灾变事件的内在规律性，即自相似性。
The burma sequences were variously developed in the sandy limestones ofGaoyuzhuang formation in Pingquan County,Hebei Province. They belongs to turbidite. Fractal and petrography analysis indicates that this kind of turbidite is related to windstorm. The authors’study suggest that there is a fractal relation between frequency andstrom strength.It reveals an internal rule in the catastroplni events.
