作者通过对区内岩石同位素年龄数据的统计分析,结合岩浆活动和海水运动的规律,初步探讨了二者之间的内在联系,认为本区岩浆活动高潮期多发生在大规模海退期及其稍晚时期,且二者存在正相关关系。造成这种现象的原因是岩浆活动与海水运动均受控于地球自转速度的变化。 Based on the statistical analysis of rock age isotope data in the region and the law of magmatism and seawater movement, the authors initially discussed the intrinsic relationship between them and concluded that the climax of the magmatism in this area occurred mostly during the large-scale regression and its Later, there is a positive correlation between the two. The reason for this phenomenon is that magma activity and seawater movement are controlled by the change of the Earth’s rotation speed.
