Abstract

An investigation was made of the dispersion patterns of copper, zinc, nickel, cobalt, manganese and sodium in the wall rocks of three sulfide deposits representative of the mineral occurrences found on the Springdale Peninsula, Newfoundland. Whole rock samples from the Lady Pond prospect, the Little Deer Mine and the Little Bay Mine were analyzed by atomic absorption spectrophotometry. -- The deposits, consisting of several steeply plunging narrow lenses containing disseminations and impregnations of chalcopyrite and pyrite, occur in chloritic shear zones in Ordovician pillow lavas. -- The sodium content of the samples gives a reliable indication of the extent of alteration undergone by the country rocks and the chlorite schist zones in which the deposits occur. Nickel and cobalt dispersion patterns do not show any aureoles surrounding the deposits. Manganese and copper dispersion patterns may exhibit narrow local aureoles. The zinc dispersion patterns suggest the presence of aureoles, approximately twenty five feet wide, around the sulfide deposits for four out of six traverses. -- Average background values have been determined for the elements studied and data are presented on the distribution of the elements between different parts of pillows found in the epidotized pillow lavas.
