DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.
3821: Electron Microprobe Analyses of 1997 Cold Bay Samples
View table data :: Download table data (.csv)
* EMP analyses of tephra samples collected by the author in 1997. Average weight percent oxide composition is given for each element with one standard deviation in parentheses. Samples with distinct multi-modal compositions have each mode listed separately as noted by suffix in parentheses following sample number. Number of analyses for each sample between 98.0% and 100.5% total weight percent listed as n. *
3831: Electron Microprobe Analyses of 1996 Cold Bay Tephra Samples
View table data :: Download table data (.csv)
* EMP analyses of tephra samples collected in 1996 and analyzed by Carson. Average weight percent oxide composition is given for each element with one standard deviation in parentheses. Samples with distinct multi-modal compositions have each mode listed separately as noted by suffix in parenthesis following sample number. Number of analyses for each sample between 98.0 and 100.5 wt. % composition given as n . *
3841: Additional Electron Microprobe Analyses of 1996 Cold Bay Tephra Samples

* EMP analyses of tephra samples collected in 1996 and analyzed by Carson. Average weight percent oxide composition is given for each element with one standard deviation in parentheses. Samples with distinct multi-modal compositions have each mode listed separately as noted by suffix in parenthesis following sample number. Number of analyses for each sample between 98.0 and 100.5 wt. % composition given as n . *
3851: Representative EMP Analyses of Rhyolitic Pumice Samples
View table data :: Download table data (.csv)
* Weight % compositions of rhyolitic pumice samples showing consistant total weight % compositions in the range of 90 - 94 %. Analysis of samples at 10 KV and analyzing for oxygen confirmed that the low totals were the result of hydration. *
3861: Normalized Weight % Composition of Rhyolitic Pumice Samples
View table data :: Download table data (.csv)
* Weight% compositions from Table 6a normalized to compensate for to hydration (Froggall, 1992) *
3871: Representative Compositions of Correlated Horizons
View table data :: Download table data (.csv)
* Representative compositions of the Cold Bay tephra horizons. Weight% compositions are the mean of all correlated samples. Horizons are listed in stratigraphic order. *
3881: Weight % Compositions of Proximal Tephra Samples
View table data :: Download table data (.csv)
* Sample 78WEST collected at Coast Guard station on Unimak Island following 1978 eruption. Sample 86AMM187 collected at Cape Lapin on Unimak Island by Dr. Tom Miller. Samples FC05, FC06, FC07, and FC19 collected by Dr. John Foumelle at Fisher Caldera. Samples SH112, SH117, SH118, SH119, and SH141 collected by Dr. Fournelle at Shishaldin volcano. *
