黑龙江省中部中低山区古冰川地质遗迹存在的可能性分析

ANALYSIS OF THE POSSIBILITY OF ANCIENT GLACIER GEOLOGICAL RELICS EXISTING IN THE MIDDLE AND LOW ALTITUDE MOUNTAINOUS AREAS IN THE MIDDLE PART OF HEILONGJIANG PROVINCE

冰川地质遗迹是冰川存在的重要依据,也是古气候变迁的历史见证。目前,在黑龙江省内4家花岗岩地貌类地质公园中皆或多或少的发现了类似古冰川地质遗迹的现象,形似冰臼、冰壁龛、冰面湖湖蚀柱石等。这一发现对于促进研究该区是否存在古冰川,并由此推断古气候、古环境演化和增加地质公园的地学价值有着极其重要的意义,通过进一步工作,很有可能最终确定黑龙江省古冰川地质遗迹的存在。

Ancient glacier geological relics are regarded as important underlying basis for existence of any glaciers and historical witness of the transitional process of climate in ancient times.Up to now,in the four geological parks with granite landforms within the territory of Heilongjiang Province,more or less signs similar to ancient geological glacier relics have been found,like ice moulin,ice niche,rock columns itched by ices on the surface of an icy lake and their similarities in shapes or morphology.Such a discovery is of an extreme importance for pushing forward a study whether or not ancient glaciers are present in the said areas and thereby judging the evolution of the paleoclimate and paleoenvironment and adding the geoscience value of the geological parks.Through an effort made afterwards,it is likely to finally determine the existence of ancient glacier geological relics in Heilongjiang Province.
