Errata and Amendments

On Preliminary Map P.3841, Precambrian Geology of Kenogaming Township, Northern Swayze Area, Abitibi Greenstone Belt, Northeastern Ontario, originally released November 2019 and updated December 2020, an incorrect reference was cited for the age of the Matchewan dike swarm in footnote “f” of the Legend. The correct reference should be Bleeker et al. (2015), not Heaman (1988). Additionally, Heaman (1988) should not have been included in the list of Geochronology references under “Sources of Information”. Additionally, the reference regarding corresponding and additional digital data related to the map has been updated to reflect the fact that Miscellaneous Release—Data 378, Geological, Geochemical and Geophysical Data Related to Penhorwood and Kenogaming Townships, Northern Swayze Area, Abitibi Greenstone Belt, Northeastern Ontario, was revised in 2021.

On Preliminary Map P.3842, Precambrian Geology of Penhorwood Township, Northern Swayze Area, Abitibi Greenstone Belt, Northeastern Ontario, originally released December 2020, an incorrect reference was cited for the age of the Matchewan dike swarm in footnote “f” of the Legend. The correct reference should be Bleeker et al. (2015a), not Heaman (1988). In the list of Geochronology references, under “Sources of Information”, Heaman (1988) should not have been included. Additionally, the first Bleeker et al. reference should be “2015a”, and the second, “2015b”. In Table 1, for sample no.5, the reference should be Bleeker et al. (2015b), not “Bleeker et al. (2015)”. Additionally, the reference regarding corresponding and additional digital data related to the map has been updated to reflect the fact that Miscellaneous Release—Data 378, Geological, Geochemical and Geophysical Data Related to Penhorwood and Kenogaming Townships, Northern Swayze Area, Abitibi Greenstone Belt, Northeastern Ontario, was revised in 2021.

New versions of these maps are available. If you purchased a copy of these maps prior to 2021 and wish to receive replacement copies, please contact Publication Sales, and new versions will be shipped to you free of charge. Alternatively, the new versions of Preliminary Map P.3841 and Preliminary Map P.3842 are available for free downloading on GeologyOntario.
