多伦地区的晚侏罗世火山岩地层,可划分为满克头鄂博、玛尼吐、白音高老三个火山活动小旋回,通过对其岩石组成、岩相、结构构造及其变化的研究,从地球历史演化的阶段性、周期性和不可逆性的角度,探讨了该区晚侏罗世火山活动节律特征,进而从时空尺度对火山活动节律的级别和特征进行了划分和厘定,并探讨了不同级别节律的成因。
Late Jurassic volcanic strata in the Duolun area can be divided into three small cycles of volcanic activity of Mancock Obo, Manitou and Baiyinao-Lao. Based on the study of their rock composition, lithofacies, structural structure and their changes From the perspective of the historical, periodic and irreversible evolution of the Earth’s history, the characteristics of volcanic activity rhythms of the Late Jurassic in this area were explored, and the levels and characteristics of volcanic activity rhythms were also classified and determined from the perspective of spatio-temporal scales The causes of different levels of rhythm.
