Analytical results and sample locality map for rock samples from the Solomon, Bendeleben, and southern part of the Kotzebue quadrangles, western Alaska

Abstract

lists the lower determination limit for each analyses are reported in parts-per-million (ppm) Fe , Mg, and Ti, which are reported in weight Analytical Results Analytical results are tabulated in table 3. Emission spectrographic analyses have a S-prefix (eg. S-Mo), atomic absorption a n a'l y s e s have an AA-prefix (eg. AA-Zn), and instrumental mercury has an I-prefix. Analyses are reported in parts-per-million (ppm) except for Ca, Fe, Mg, and Ti, which are reported in percent. Two elements that were analyzed for are not shown in table 3. S-Au was above the lower determination limit in only 4 samples-30 ppm in 83Ge027a, and 50 ppm in 83Ge026a, 83Ge026d, and 83Gel40; and was detected but below the lower determination limit in an additional 4 samples-83Gel38, 83Gel41, 84Ge041e, and 84Kn069. S-Th was at or above the lower determination limit in only 4 samples-100 ppm in 84Ge050a, 150 ppm in 84Ge 075a, and 200 ppm in 82Du036c; and was detected, but below the lower determination limit, in 7 samples: 82C1105c, 83Dn047a, 83Ge070a, 83Gell5a, 83Gel22, 83GHel47 and 83Til42a. The following abbreviations and symbols are used in Table 3. 1) Latitude and longitude are in degrees-minutes-seconds. 2) Quad. = The 1:63,360 quadrangle that the sample location is in; S = Solomon, B = Bendeleben, K = Kotzebue. 3) gx code = rock type (see table 2) 4) S = semiquantitative spectrographic analysis, AA = atomic absorption analysis, I = Instrumental analysis. 5) Standard chemical symbols are used for all elements.

Maps showing metallic mineral resources of the Bendeleben and Solomon quadrangles, western Alaska

“…The most notable examples of this deposit type in the Bendeleben and Solomon quadrangles are the Big Hurrah Mine and the Bluff deposits. In addition to these two deposits, many other prospects and occurrences are present in these quadrangles (Gamble, 1988). Low-sulfide gold-quartz veins in the Nome quadrangle, to the immediate west of the Solomon quadrangle, are present in the same host rocks along similar structures.…”

“…Several occurrences in the western part of the Solomon 14 quadrangle (Gamble, 1988;map nos. 97, 98, 124, 128, 129, 130) may be related to Besshi-type deposits, or alternatively, to sandstone-hosted Cu deposits.…”

“…However, the lack of any other geochemistry (Gamble and others, 1988), stream-sediment and indicators such as silicification or anomalous geochemistry panned-concentrate geochemistry (King and others, 1989a;Smith precludes evaluating the favorability of these areas. Other and others, 1989), geophysical data (Cady and Till, in press), and mineral-deposit types that are considered permissive are known mineral occurrences (Gamble, 1988), the Bendeleben and sedimentary rock-hosted Au-Ag ("Carlin"-type gold), Mississippi Solomon quadrangles are favorable for the following mineral…”
