INTERPRETATIONS OF COMPLICATED FOLDED STRUCTURES AT THE LOWER PARTS OF ANTARCTIC AND GREENLAND ICE SHEETS
Complicated folded structures were recently recorded by radar survey in the lower portions of the Antarctic and Greenland ice sheets. From a geological point of view the Antarctic and Greenland ice sheets are considered as geological features, while the ice is classified as sedimentary or metamorphi...

Complicated folded structures were recently recorded by radar survey in the lower portions of the Antarctic and Greenland ice sheets.

This study considers the processes of three kinds of tectonic structures: glacial diapirs, glacial diapir folds and glacial intrusions.
