Sediments of the Warta ice-sheet deglaciation in the eastern part of the Łódź region
The author attempts at formulating a synthetic description of geological and geomorphological effects of the Wartanian ice-sheet deglaciation in the eastern part of the Łódź region, taking their spatial variability into consideration.

The author attempts at formulating a synthetic description of geological and geomorphological effects of the Wartanian ice-sheet deglaciation in the eastern part of the Łódź region, taking their spatial variability into consideration.
