【摘要】 在地质历史中,地球曾发生过震旦纪冰川、石炭-二叠纪冰川和第四纪冰川3次冰川活动。为研究和预测当今气候,按照岩石学原理和李四光教授创立的确定古冰川的3个标准,研究了渝鄂湘黔毗邻地区的古冰川事件,结论是该区只发生过震旦纪冰川;第四纪时不存在古冰川遗迹,没有发生过冰川活动;为温暖湿润气候。更多还原

【Abstract】 At the geologic time,the earth had undergone the glacial stages:Sinian ice age,Carboniferous~Permian ice age and Quaternary ice age.According to the theory of petrology and three standards of professor Li Siguang to determine fossil glacier,the result of the research indicated that at boundary of Chongqing,Hubei,Hunan and Guizhou provinces only undergone Sinian ice age.There is not the remnants of Quaternary fossil glacier here.So the climate is warm and moist.更多还原
