The Missinaibi Formation is a Late Pleistocene geologic formation in the Hudson Bay Lowlands in Northern Ontario, Canada. [1] The formation lies within Missinaibi Provincial Park. [2]
It was first identified by geologists in the late 19th century. [3] The Missinaibi Formation is principally known for having nonglacial sediments, which means that dating the formation has helped scientists track the ebb and flow of glacial activity in the region. [1] [3]
Scientists have found fish and beaver remains dating from the Sangamonian interglacial [4] The formation also preserves fossils of mastodon. [5]
In 1958, Algoma Ore Properties surveyors identified two iron ore deposits with an airborne magnetometer and staked mining claims. [6]
