ABSTRACTIn Quaternary sandy glacial outwash sediments situated in the Inn Valley NE of Innsbruck (Austria) occur redeposited diamicton blocks containing flatiron-shaped and ice-striated pebbles. Associated with these blocks are small, graben-like structures offset by small highangle faults (“ice-melt graben structures”) interpreted to have been caused by the melting of underlying ice-rich blocks. The diamicton blocks most likely originated from frozen glacial sediments, probably tills from the advancing Inn Glacier by fluvial erosion and are believed to be a prominent indicator for periglacial environments.
