The search for diamonds in Manitoba - an update 

 

The Manitoba Geological Survey has undertaken a number initiatives to assist in the search for diamondiferous kimberlite in the province including:

  • a compilation of existing data from a number of surveys and agencies into a single comprehensive database of public-sector survey results released as Manitoba Kimberlite Indicator Mineral Database,
     
  • ongoing analysis and 3-D modelling of till stratigraphy in the Hudson Bay Lowland, and
     
  • the compilation of potential-field data, structural data and ‘young’ igneous occurrences.

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.

 

Manitoba Kimberlite Indicator Mineral Database
Version 3.1.1

Manitoba Kimberlite Indicator Mineral Database

by G.R. Keller
(zipped Microsoft® Access 2007 database, 2.5 MB)
Supersedes OF2003-3, OF2004-1, OF2004-2 and OF2004-25

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 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.

Download version 3.1.1

Version 3.1.1 is a data ‘fix’ version. This release resolves a data issue found with OF2002-1 and GP2002-1.  All other functionality in this database is the same as version 3.1.  Version 3.1.1 WILL NOT function with Access 2003 and lower. For those using Access 2003 or lower and/or wish to have the Shapefile export and Shapefile viewing functionality, the older version 3.0 of the database with that functionality is included below.

Manitoba Kimberlite Indicator Mineral Database
Version 3.0

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.

A ZIP file containing the Microsoft® Access 2000 database and associated files for this report is available to download free of charge at http://www.gov.mb.ca/iem/info/libmin/OF2004-25.zip
IMPORTANT NOTE: Version 3.0 was superceded by version 3.1.1 which can be downloaded here.

 

Manitoba's Integrated Anomaly Map

Compilation of structural, topographic, potential field and geologic data focussed toward identifying deep crustal structures and occurrences of kimberlite.
