Mineral Chemistry of Some Metamorphosed Shuswap-area Mineral Deposits (82l,m)

This paper is an initial report on the mineral chemistry of four metamorphosed stratabound mineral deposits which are located within or adjacent to the Shuswap Complex. These are commonly referred t” as Cottonbelt, CK, Goldstream and Big I.edge deposits. Rock specimens were selected from those collected by Trygve H6y of the British Columbia Geological Survey Branch. The particular specimens chosen were “ot selected specifically to be reprrsentative of each deposit as a whole but rather as examples of the assemblage sphalerite-pyrrhotite-pyrite, in order to test the proposed sphalrrite geospeedometer (Bartholomew and Lasaga, lYY2). However, since very few data “n the chemistry of minerals within these deposits has previously been reported, this paper was written in order to begin to c”rrect this deficiency. After reviewing the mineralogy of each of the selected specimens, one was chosen from each deposit for analysis. Only t~hese four specimens are described here.
