本文在冰期形成的天文、地质因素分析基础上,提出了以下几点认识:1.提出冰期是在一定的天文-地质因素相迭加、共振作用下形成的。2.认为黄道倾斜(ε)的变化贯穿于整个地质时代的气候变化之中,是影响冰期形成的重要天文因素。3.根据冰期成因的迭加-共振模式,对晚元古代冰期的成因进行了初步探讨。4.对晚元古代冰川活动的范围、次数、时限、等时性及非等时性等问题,进行了讨论。
Based on the analysis of the astronomical and geologic factors formed during the glacial period, the dissertation puts forward the following points: 1. It is proposed that the glacial stage was formed by the superimposition of certain astronomical-geological factors and resonance. 2. It is considered that the change of the ecliptic slope (ε) runs through the climatic changes of the entire geological era and is an important astronomical factor that affects the formation of the ice age. According to the superposition-resonance model of the genesis of the Ice Age, the origin of the Late Proterozoic glacial period was discussed. 4. Discuss the range, number, time limit, isochronous and non-isochronous nature of the late Proterozoic glacier activities.
