A study of 164 samples of sphalerite, of which 122 are from Western Canada, has confirmed the results of other workers in this field, and particularly those of Stoiber.Western Canada, as a metallogenetic province, is high in gold and tin, but is low in gallium, germanium, and vanadium. Within Western Canada there are many definite districts, each of which tends to show a characteristic minor element assemblage.The relative abundance of the various minor elements which have been studied is discussed, and the characteristic distribution of some of these minor elements in a few important areas is noted.As an important by-product of these studies, an apparent relationship is shown between the depth to which orebodies containing native gold and silver persist and the amount of manganese present in associated sphalerite.
