Various theories of genesis have been investigated by the Rb-Sr geochronologic method. t~b-Sr measurements on early stage pegmatite minerals indicate an age of 258 โข 1 m.
The Rb Sr composition of eight melt rock and three basement samples from the East Clearwater impact structure, Quebec, and two basement samples from the West Clearwater structure has been determined. The whole rock STSr/S6Sr ratios of the melt samples, 0.7167-0.7253, are within the range of the base
