太白山是秦岭山脉的最高地带,主峰八仙台海拔3767米。根据冰川遗迹的分析有以下几点特点: 1、属冰斗悬冰川和小型谷地冰川; 2、串珠状冰湖和冰坎发育,表明冰川虽属小型,但很活跃,有小的进退; 3、一方面具有大陆型低平衡冰川类型的特点,另一方面又表现为具有海洋性冰川的性格。这种具有双重性的特点与太白山所处的地理位置是统一的,即具过渡性性质; 4、从雪线的高度(海拔3600米)、冰川的规模(小型)、冰碛物的风化状况,以及较老石海、石河的分布,表明这一冰川作用可能与晚更新世晚期的冰期相当。
Taibai Mountain is the highest zone of the Qinling Mountains, the main peak of eight Immortals 3767 meters above sea level. According to the analysis of glacial relics has the following characteristics: 1, ice bucket suspended glacier and small valley glacier; 2, beaded glacier and ice ridge development, indicating that the glacier is small, but very active, with small advance and retreat; On the one hand, it has the characteristics of a continental type of low-balance glacial glacier, on the other hand, it has the character of a marine glacier. This duality is consistent with the geographic location of Taibai Mountain, that is, the transitional nature; 4, from the height of the snow line (3600 meters above sea level), the size of the glacier (small), the weathering of the moraine , And the distribution of the older Shihai and Shihe shows that the role of this glacier may be equivalent to that of the Late Pleistocene.
