Potassium-argon and argon-argon dating can be used to date the formation of volcanic rocks.
Older marine sediments can be dated using palaeo-magnetism.
This is because the earth’s magnetic field varies in strength and polarity direction.
This is caused by a number of factors, including variations in solar radiation, magnetic storms, and internal geophysical factors.
As glacial geologists, some of the biggest questions that we’d like to answer are not only how large former ice sheets were, but also how fast did the recede and how quickly did they thin?
This information is vital for numerical models, and answers questions about how dynamic ice sheets are, and how responsive they are to changes in atmospheric and oceanic temperatures.
Organic matter needs to have been buried and preserved for this technique. It assumes that organic material is not contaminated with older radiocarbon (which, for example, is a common problem with organic material from marine sediment cores around Antarctica).
Unfortunately, glacial sediments are typically difficult to date.
Most methods rely on indirect methods of dating subglacial tills, such as dating organic remains above and below glacial sediments.
