citation imagePreece, S. J., Westgate, J. A., Alloway, B. V., and Milner, M. W., 2000, Characterization, identity, distribution, and source of late Cenozoic tephra beds in the Klondike District of the Yukon, Canada: Canadian Journal of Earth Sciences, v. 37, n. 7, p. 983-996.

DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.
3621: Average glass major-element compositions of type I beds and Archibald tephra in the Klondike area.
View table data :: Download table data (.csv)
* Note: All analyses done on a Cameca SX-50 wavelength dispersive microprobe operating at 15 keV accelerating voltage, 10–15 micron beam diameter, and 6 nA beam current. Standardization achieved by use of mineral and glass standards. Analyses recast to 100% on a water-free basis. (#), standard deviation; n, number of analyses; FeOt, total iron oxide as FeO; H2Od, water by difference. Average composition based on non-zero values for the following samples: Dawson (UA68, UA69, UA581, UA582, UT11, UT12, UT18, UT20, UT540, UT719, UT1056, UT1057, UT1059, UT1061), Old Crow (UT17), Mosquito Gulch (UT19), Dominion Creek (UT1456), and Archibald (UT1453) tephra beds. *
3631: Average glass major-element compositions of type II tephra beds in the Klondike area.

* Note: Operating conditions (as specified in Table 2): All analyses done on a Cameca SX-50 wavelength dispersive microprobe operating at 15 keV accelerating voltage, 10–15 micron beam diameter, and 6 nA beam current. Standardization achieved by use of mineral and glass standards. Analyses recast to 100% on a water-free basis. (#), standard deviation; n, number of analyses; FeOt, total iron oxide as FeO; H2Od, water by difference. Average compositions in wt.% are based on the following samples: Bonanza Creek (UT1055, UT1454, UT1457), 80 Pup (UT14), Sheep Creek (UT104, UT1058, UT1060, UT1064, UT1065,UT1459, UT1460, UT1461, UT1462), Preido Hill (UT105, UT106, UT107), Last Chance Creek (UT16, UT92, UT108), Little Blanche Creek (UT1054, UT1455), and Quartz Creek (UT1001, UT1053) tephra beds. *
