一、前言1970年初,按照李四光同志的布署,我们有机会参加一项生产会战任务。即在湘西、黔东地区(图1)试用第四纪冰川方法提供找矿线索。积五年实践所获,如若单从第四纪冰川方面总结而言,可以说再次证实在湘西、黔东地区曾经发生过多次冰川活动。由冰期、间冰期叠次更替的事实表明:那里的第四纪气候不是一成不变的。各期冰川的滋生、运行及消亡都有其自身的规律性。第四纪冰川作为一种地质营力,极为清楚地显示它对第四纪地层、地貌及生物等等方面,均产生广泛而深刻的影响。
I. Introduction In early 1970, following the deployment of Comrade Li Siguang, we had the opportunity to participate in a production battle mission. That is, in western Hunan, Qiandong area (Figure 1) trial quaternary glacier method to provide prospecting clues. It is argued once again that the glacier activities have taken place in western Hunan and Qiandong areas for several times in the light of the conclusions of Quaternary glaciers. The fact that the glacial period and the interglacial period were alternately replaced indicates that Quaternary climate there is not immutable. All kinds of glaciers have their own regularity in breeding, operation and demise. The Quaternary glacier, as a kind of geological force, shows very clearly that it exerts extensive and profound influence on Quaternary stratigraphy, geomorphology and biology.
