Schematic of glacial dispersal of spodumene grains from bedrock into glacial sediments at surface. A buried spodumene pegmatite has been eroded by southwesterly flowing ice during the last glaciation event which has mechanically transported boulders of spodumene pegmatite, as well as spodumene grains, from the bedrock source into the overlying glacial sediments (modified from McClenaghan 2017).
