摘要
本文根据大量的文献资料和笔者的研究成果,从火山岩的时空分布出发,论述了安徽磨子潭-晓天地区中生代火山岩的地质特征,讨论了火山岩的形成时代,并对火山喷发旋回的划分进行了探讨。
This paper, based on considerable documents anu the author's, resarch results has from the angle of temporal and spatial distribution of rocks, demonstrated geological characteristics of the Mesozoic volcanics, discussed their formation time and researched into volcanic eruption cycles in the Mozitan -Xiaotian area of Anhui Province.
