"Ore samples consisting of diamond drill core and mine samples, collected from several Balmat ore bodies, were analyzed for their mercury content. The average contents in these ore bodies were found, in ppb, to be: Upper Gleason, 829; Middle and Lower Gleason, 504; Loomis, 546; Fowler, 195; No. 1 Zone, 37; Sylvia Lake, 59; No. 2 Mine, 5. If all of the mercury in these pyrite-sphalerite-galena ores occurs in the sphalerite, then the average sphalerite mercury contents, in ppb, are the following: Upper Gleason, 2490; Middle and Lower Gleason, 2516; Loomis, 2701; Fowler, 1376; No.1 Zone, 384; Sylvia Lake, 408; No. 2 Mine, 34. This sequence is the same as that above, in which the lower an ore body occurs stratigraphically the higher its mercury content.
The most interesting feature of the results of this research is an upward stratigraphic decrease in mercury concentration, not only from deposit to deposit upward through the stratigraphic column, but also within a single ore body. The Fowler and No. 1 Zone ore bodies illustrate, particularly well, the upward decrease in mercury in single ore bodies. The Upper Gleason ore body, which is overturned due to folding, exhibits an overturned mercury pattern in which mercury decreases downward. This indicates that the pattern of mercury distribtution [sic] was developed prior to folding and metamorphism"--Abstract, page ii.
