AbstractEffective and efficient diamond exploration in glaciated terrain calls for a thorough knowledge of the glacial geology of the area concerned. Drift prospecting relies on the identification of dispersal trains in glacial drift (cf. DiLabio and Coker 1989; Kujansuu and Saarnisto 1990; Bobrowsky et al. 1995; McClenaghan et al. 2001; Paulen and McMartin 2009). Kimberlite exploration in the Western Canada Sedimentary Basin is hampered by a highly variable overburden thickness, paucity of outcrop and a complex glacial and deglacial history, with more than one Pleistocene glacial event affecting most of western Canada. Glacial ice has played the principal role in the transportation of indicator minerals. As a general rule, tills containing these trains occur in thin deposits, less than 5 m thick, generally deposited in a straight-line trajectory derived from local bedrock, or in thick deposits, tens of metres thick, with a complex history of
