The composition reported here is the average of analyses of two samples: UT819, and UT886.

L.||< 2020000 ± 140000 stratigraphy; 996; Weighted mean average of two dates obtained on sample UT497, which is strategraphically below this sample (therefore this sample is younger). See Preece and others (1999) for methods.||Late Cenozoic tephrochronological record of the Fairbanks area, Alaska. Tephra in the Gold Hill Loess and in sediments younger than the Gold Hill Loess. Glass geochemical data averages here are calculated from analyses of multiple tephra correlated across different stratigraphic locations in the Fairbanks area. Individual sample IDs are noted in the sample descriptions. Note that tephra units only located in one stratigraphic section are not included here and are listed by individual sample ID (see Pewe et al., footnotes of tables 1, 2, and 3).||The composition reported here is the average of analyses of two samples: UT819, and UT886.||Pewe_2009_Gold_Hill_Loess_PH_average||Tephra Fall||Cumulate||Glass||77.41||0.13||13.27||0.96||0.07||0.25||1.37||3.71||2.66||4792||EMP||0.96||Cl=0.19; H2O=5.23||EMP|
