New work has shown that kimberlite indicator
minerals in till within the Hudson Bay Lowland occur
preferentially within one of four till units. Ice
flow directions derived from till fabric analysis
and indicator distributions suggest indicator
minerals were dispersed by ice flowing to the
southeast in addition to regionally pervasive
southwesterly ice flow events.
New bedrock studies show that the northwest Superior
Province boundary contains an ancient platformal
supracrustal sequence that stabilized prior to 3.0
Ga. The combination of this potentially thick
lithosphere and Mesozoic hotspot tracks suggests
that this region should host kimberlites.

This searchable database contains a compilation
of results from all available, non-confidential,
kimberlite indicator mineral surveys completed in
Manitoba. The database houses sample location,
sample preparation and reference data as well as
microprobe analyses of heavy mineral grains. The
database includes new data from De Beers Canada
Exploration Inc. as well as data from Indicator
Explorations Ltd., Kennecott Canada Explorations
Inc. and the Erik Nielsen 2002 Hudson Bay Lowland
survey.
The database can be searched by geographic area
and/or mineral or chemical attributes using basic
database search techniques. Version 3.0 features a
customised query form providing additional query
options to facilitate searching as well as the
ability to create and view Shapefiles from queried
data.
Version 3.0 of the Manitoba Kimberlite
Indicator Mineral Database supersedes previous
versions.
