Project Description

Main objectives:

The overall objective is to provide a comprehensive update to the 1959 report of “Gypsum-Anhydrite deposits of Manitoba” produced by B.B. Bannatyne (MGS Publication 58-2, which reviewed the previous 58 years of the gypsum industry in Manitoba).

Methodology:

  • Compilations of published and unpublished reports and assessment files, focusing on historical production and important events in the history of gypsum mining/quarrying.
  • Detailed geological descriptions of Manitoba gypsum deposits and occurrences, primarily within active quarries.
  • Examination of drill cores and thin sections.
  • Performing isotopic analysis of key stratigraphic sections and cores to perform stratigraphic correlations between various gypsum deposits.

 

Benefits:

The project addresses a need to document and provide current geoscientific information on a commodity (gypsum-anhydrite and its value-added products, e.g. wallboard) to industry and the public that is extremely valuable to the future industrial development of Manitoba’s Capital Region, and to the province as a whole.

 

Plans for fiscal year 2017-2018:

  • Submit samples for isotopic analyses for stratigraphic correlations.
  • Prepare final report.
