DATA TABLES *Not all tables in a publication may be listed. Not all tables from a publication have data entered in the database.
3701: Major element composition of Northern and Eastern Lobes of the White River Ash
View table data :: Download table data (.csv)
* Note. Major element-element analyses done on a JEOL superprobe operating at a 15keV accelerating voltage, 5 mm [sic? Should this be microns?] beam diameter, and 6nA beam current at the University of Alberta. Standardization to obsidian standard UA5831, recast to 100% on a water-free basis; (#)= standard standard deviation; n =number of analysis; FeOt =total iron oxide as FeO; H2Od =water by difference. *
3711: Average glass major-and trace element compisitions [sic] of Sheep Creek-like tephra beds.
View table data :: Download table data (.csv)
* Notes: All major-element analyses done on a Cameca SX-50 wavelength dispersive electron microprobe. Trace-element analyses for Ash Bend, SCT-K and SCT-F performed by solution nebulisation inductively coupled plasma mass spectrometry (ICP-MS) using a VG Plasma-Quad PQ II. Trace-element analyses for SCT-C performed by laser ablation ICP-MS using a Mercantec LUV266 laser ablation system and a VG Plasma-Quad PQ II. Major-element 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; n.d. =not determined. *
3721: Major and trace element composition of glass shards from tephra beds within Midnight Dome Loess.

* Notes: All major-element analyses done on a Cameca SX-50 wavelength dispersive electron microprobe. Trace-element analyses performed by solution nebulisation inductively coupled plasma mass spectrometry (ICP-MS) using a VG Plasma-Quad PQ Il. Major-element 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. Note that this composition of the Midnight Dome tephra was previously reported by Westgate et al. (2001) and is therefore not included in this table. *
3731: Average glass major- and trace-element compositions of VT tephra bed at Fairbanks AK and Jackson Hill, YK.
View table data :: Download table data (.csv)
* Notes: All major-element analyses done on a Cameca SX-50 wavelength dispersive electron microprobe. Trace-element analyses for VT at Paradise Hill performed by solution nebulisation inductively coupled plasma mass spectrometry (ICP-MS) using a VG Plasma-Quad PQ II. Trace element analyses for VT at Fairbanks performed by the instrumental neutron activation technique (INAA). Major-element 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; n.d. = not determined. Note that the VT tephra composition in Fairbanks is reported in this table; however, these analyses of this tephra were previosly reported in Preece et al. (1999) and therefore the are not re-entered into the database. *
3741: Average glass major- and trace-element compositions of tephra beds in the Paradise Hill Area.
View table data :: Download table data (.csv)
* Notes: All major-element analyses done on a Cameca SX-50 wavelength dispersive electron microprobe. Trace-element analyses for Paradise Hill and Dago Hill performed by solution nebulisation inductively coupled plasma mass spectrometry (ICP-MS) using a VG Plasma-Quad PQ II. Trace-element analyses for Little Blanche Creek performed by laser ablation ICP-MS using a Mercantec LUV266 laser ablation system and a VG Plasma-Quad PQ II. Major-element analyses recast to 100% on a water-free basis; (#) = standard deviation; n = number of analyses; FeO = total iron oxide as FeO; H2Od =water by difference; n.d. =not determined. Note that the composition of the Little Blanche Creek tephra at Quartz Creek is reported in this table; however, the same analyses of this tephra were previously by Preece et al. (2000) and there are not re-entered into the databse. *
3751: Average glass major- and trace-element compositions of Quartz Creek tephra bed.

* Notes: All major-element analyses done on a Cameca SX-50 wavelength dispersive electron microprobe. Trace-element analyses performed by solution nebulisation inductively coupled plasma mass spectrometry (ICP-MS) using a VG Plasma-Quad PQ II. Major-element 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. *
3761: Average glass major- and trace-element compositions of Lucky Lady tephra.
