AbstractLarge quantities of three samples of sulphide-bearing ultramafic rock have been collected; two from the Werner Lake-Gordon Lake district of northwestern Ontario and one from the Gi ant Mascot Mine at Hope, B. C, The latter sample is a peridotite; the other two are serpentinized hornblende metaperidotites. All three samples have been crushed, ground, and thoroughly homogenized before being analyzed for a number of elements . The primary purpose of the samples is to provide standards for the determination of S and ascorbic acid-hydrogen peroxide soluble Cu, Cu, Ni, and Co in ultramafic rocks. Analysis for these components forms the basis of a geochemical method for evaluation of the ore potential of ultramafic rocks. Repeated determinations of the latter three components using a two-way analysis of variance design shows that each of the samples i s homogeneous for these components. The samples may also prove to be useful standard material for other elements, such as chromium and the platinum metals. They have been analyzed for Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, P, HzO, COz, Cr, Zn, and total Cu, Ni, and Co in addition to the components listed above. Bottles of each of the standards U,M, 1, U. M. 2, and U. M, 4 are being distributed by the Canadian Standard Reference Materials Project.
