| 31. | The results of this unique freeze-thaw cycle are customarily found in Arctic periglacial regions of Eastern Siberia and Alaska.
|
| 32. | In addition to periglacial and coastal refugia, there were also possible areas of embedded refugia in Patagonia and New Zealand.
|
| 33. | They originated mainly under periglacial conditions, i . e . during the course of the ice ages, and their retreat.
|
| 34. | These barren block fields occur in periglacial environments where outcrops of resistant rock are exposed with a slope of less than 25?
|
| 35. | This is mainly due to erosion during the sustained permafrost and tundra like conditions in the periglacial zones of multiple ice ages.
|
| 36. | Brickearths are periglacial loess, a wind-blown dust deposited under extremely cold, dry, peri-or postglacial conditions.
|
| 37. | Many of the landforms resemble periglacial features seen on Earth, such as moraines, ice-wedged polygons, and pingos.
|
| 38. | Periglacial boulder fields are present on both sides of the water gap, and the boulders are formed of the Silurian Tuscarora Formation.
|
| 39. | Periglacial phenomena are observed on Llullaillaco, commencing at altitude and reaching their maximum around on the Chilean and on the Argentine side.
|
| 40. | This is material which drifted down the slope which we have followed, while it was under the water of the Devensian periglacial lake.
