Nauyat Formation

The Nauyat Formation is a geologic formation on northwestern Baffin Island in Nunavut, Canada, composed of continental flood basalt lava flows linked to the Mackenzie Large Igneous Province. At least 360 meters thick, these volcanic rocks date from about 762 to 1,221 million years ago, spanning the Mesoproterozoic to Neoproterozoic. The formation preserves evidence of immense ancient basaltic lava outpourings and forms part of the deep volcanic history of northern Canada.
