摘要：AbstractThe debris-covered glaciers are observed all over the glaciation regions of the world (Alps, Antarctica, Greenland, Andes, Cascades, Rocky Mountains and etc.). The debris covered glaciers are known as the formations which occur in the retreating phase of glaciers and sometimes they are confused with rock glaciers. In this study, hypothesis that debris covered glaciers existed in glaciation fields with similar conditions during the previous glacial periods in Pleistocene is questioning. The experiences which are acquired from actual glaciers in Taurus range and the researches that have been done in the other glaciated valleys of the world shows apparent evidence that there were debris-covered glaciers in the past glacial periods and also debris layer can be found during the advancing phase of a glacier. From the valleys that are occupied with debris-covered glaciers the following conclusions have been extended. When they have compared to past bare glaciers, past debris-covered glaciers a) responded later to warm air and temperature rise, b) advanced to lower altitudes, c) experienced different sediment transport and deposit from bare glaciers, d) didn’t experienced ablation from the surface of the glacier slowly, but faster ablation due to collapsing and calving of subglacial-englacial channels, e) maintained themselves as fully covered dead ice/glaciers in protected cirque areas in the last stage of glaciation. If the retreating of the glacier continues until it is completely covered by the debris layer, than it may become an ice-cored rock glacier.
