|Gold Hill Loess Regional Tephra||64.9||-147.89997||Preece, S. J.||Tephra occuring primarily in the Gold Hill Loess, Gold Hill area of Fairbanks, Alaska. Tephras identified in 13 stratigraphic sections in the area; geochemical data of samples reported here are averages calculated from analyses of multiple tephra correlated across different stratigraphic locations in the 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 Preece et al. 1999 footnotes of tables 1 and 2).||Typically found as a relatively thick bed and is composed of bubble-wall shards with minor pumice.
