ABSTRACT
Salt glaciers are extrusions of rock salt emerging from the crests
of exposed salt domes. Present-day examples of salt glaciers are found
in Iran but are also present in far greater abundance buried in sedimentary
basins such as the Gulf of Mexico. The talk is illustrated with spectacular
and exotic images taken from space showing ice glaciers in Patagonia and
Alaska and salt glaciers in Iran. There are also plenty of ground photographs
showing what its like to climb on a salt glacier.
Martin describes the
talk as follows, "The presentation is designed to introduce the amazing
topic of salt glaciers to an audience of nongeologists. A minimum of jargon
will be used. Guaranteed free of boring graphs and strain ellipses."
