Till, Esker, Indicator minerals
Till sampling survey, NTS 55M/7, 10, MacQuoid Lake area, Nunavut, 1998-1999.
(requires an Internet connection)
In the summers of 1998 and 1999, a total of 63 samples of till and glaciomarine sand were collected in the MacQuoid Lake area, Nunavut. The sample density was 1 sample/4-5 km2. Three soil profiles were also sampled in mudboils at sites representative of different sediment types. Sand and gravel samples were also collected at 15 sites from reworked esker deposits. An additional 9 samples were collected outside the study area but within NTS 55M. Six were collected as part of NW-SE transects and the other three were collected in the Falcon zone of gold mineralization. The data are published in Geological Survey of Canada Open File 3944.
The kimberlite indicator mineral data are published in Geological Survey of Canada 1575.
