P., 1985, Distribution, stratigraphy, petrochemistry and palaeomagnetism of the late Pleistocene Old Crow tephra in Alaska and the Yukon: Canadian Journal of Earth Sciences [Journal Canadien des Sciences de la Terre], v. 22, n. 6, p. 893-906.

DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.
3551: Average composition of glass shards from Old Crow tephra
View table data :: Download table data (.csv)
* Notes: Major-element analyses (in weight percent, water free) were made on an ETEC Autoprobe fitted with an Ortec Si(Li) detector. Microprobe operated at 20 kV with a beam current set to given 3000 counts/s on willemite (~90 nA); sample current ~150 pA; counting time 100s; beam diameter ~1 micron. Data reduction by a modified version of PESTRIPS. Total Fe is given as FeO. The mean +/- SD is given, and n = number of analyses. Glass standards UA5831, CAM 66, and KN-18 were used. *
