The geologic history Canada dates back over billion years. Cobalt is a small mining town in Ontario which is well-known for its large deposits of silver, and has a very interesting geologic history. The lowermost rocks in Cobalt belong to the Canadian Shield, as described above. The area studied lies southeast of Lake Temagami in Northern Ontario and comprises 30 miles of the contact between the Temiskaming and Grenville sub-provinces, two divisions of the Canadian Shield. The age relationship between these sub-provinces has long been a problem, and the present work was undertaken to obtain further information toward a.
Cobalt, Ontario, is renowned for the billion grams ( million ounces) of silver produced from the area since discovery in by workers of the Timiskaming and Northern Ontario Railway. Native silver generally occurs with cobalt arsenides and sulfosalts in near-vertical carbonate veins cutting the Huronian sedimentary rocks of the. Northern Ontario a Vast and Magnificent Land. Northern Ontario is a unique land sculpted by geology, tempered by climate. Imagine more than a million square kilometre expanse of Precambrian forests and lakes punctuated occasionally by towns and cities — a contrast to the flat, populous, lowland area that is southern Ontario.

The geology of the buried Precambrian basement under Manitoulin Island in northern Lake Huron, Ontario, has been re-evaluated on the basis of aeromagnetic data, well cuttings, core samples, and rubidium–strontium and uranium–lead geochronologic data on some of the subsurface samples.
The Cobalt Embayment is a large (~60, km 2), irregular domain of Paleoproterozoic (– Ga) siliciclastic sedimentary rocks (i.e., the Huronian Supergroup) that unconformably overlies Archean basement rocks of the Abitibi greenstone Nipissing Diabase, regionally distributed complex of mafic sills and dikes intruded the Huronian sedimentary rocks ca.
