Bundle Description

Heavy mineral concentrates were picked for kimberlite indicator minerals (including pyrope garnet, eclogitic garnet, chrome diopside, magnesian ilmenite and chromite) by I and M Morrison of Delta BC from the 47 till samples collected in the Point Lake mapsheet (NTS 86H) in 1994.  The 0.25 to 0.5 mm fraction was picked.

These data are published in GSC Open File 3341 (table 2).  Note that the mineral identifications reported in OF 3341 are based on subsequent electron microprobe analysis, and do not always correspond to the initial visual identifications by I and M Morrison.  The visual identification data were not reported.
