摘要
本文在综合前人成果及作者成果基础上,试图对世界和中国前寒武纪各种主要地质事件的时间、序列、性质、表现及相互关系等进行系统的总结与对比,初步论述了这些地质事件在横向(区域上)的差异性和不平衡性,以及向上(时间上)的周期性和旋回性。
Based on previous workers' findings and my works,this paper is trying primarily and systematically to summarize and compare the main geological events which occured during the Precambrian Period in such aspects as their time,sequence,nature,appearanees, mutual relationship and others.This paper has also described the transverse (regional) differences and longitudinal Periodicity.
