It was defined in well Imperial Herald 1-31-1-20W2M by the Lower Paleozoic Names and Correlations Committee of the Saskatchewan Geological Society in 1958.[2]
The Herald Formation is composed of dolomiticlimestone and dolomite, which can be microcrystalline, argillaceous or microlaminated. [1] In the centre of the basin, it is represented by anhydrite.
Distribution
The Herald Formation reaches a maximum thickness of 38 metres (120 ft) in the Lake Alma area.[1]
