Optically stimulated luminescence dating of fluvial deposits

See: The types of landforms that are generated are particular to glacier flow, basal processes, the substrate (soft and deformable? ), the basal driving stress and thermal regime, and the ice temperature. Lundqvist, J., Lillieskold, M., and Ostmark, K., 1995.

There is a huge variety of glacial landforms recognised in the geological record.

However, they are difficult to see in Antarctica, because they are usually buried beneath ice.

On a few small islands around the Antarctic Peninsula, however, you can see evidence of past glaciations through glacier sediments and landforms.

On the next few pages, you can learn more about different kinds of glacial landforms found around Antarctica.

The next section contrasts these different environments and their landforms.

Some of our examples of glacial landforms come from James Ross Island, which is located on the northeast tip of the Antarctic Peninsula, at about 64°S (see map below)[1].

The area was glaciated during the Last Glacial Maximum, with around small glaciers on Ulu Peninsula.

The onshore glaciers around the Antarctic Peninsula, instead, are polythermal or cold-based. A., Shimokawa, K., Takahashi, N., Sone, T., and Trombott, D., 1992.

The contrast between landforms being made by different processes is clear around the Antarctic Peninsula. Permafrost occurrence of Seymour Island and James Ross Island, Antarctic Peninsula region, in , N.

Small islands and ice-free areas, such as James Ross Island, are characterised by small moraines made by polythermal glaciers. Holocene deglacial history of the north east Antarctic Peninsula – a review and new chronological constraints.

However, on the continental shelf, there are large landforms generated by ice streams at the Last Glacial Maximum (LGM).
