Abstract
A preliminary study of the mineralogical composition of the fine sand fractions of 51 samples of tills and stratified sands in northern Ontario was carried out. About 40 different minerals were identified in widely varying amounts. In all but a few samples, feldspar was the most abundant mineral while quartz was never the most abundant. Several deposits containing Palaeozoic limestone and dolomite fragments from the rocks of the James Bay lowlands were quite similar in composition to the calcareous southern Ontario deposits. Other samples, containing large amounts of pyroxenes, shale fragments or "greenstones", differed greatly from similar deposits in southern Ontario. The composition of the fine sand correlated well with the field classification of soils in this region, with a few exceptions.
