University of Wisconsin Radiocarbon Dates XXVI
Abstract
Procedures and equipment used in the University of Wisconsin laboratory have been described
in previous date lists (Bender, Bryson & Baerreis 1965; Steventon & Kutzbach 1986). Except as
otherwise indicated, wood, charcoal and peat samples are pretreated with dilute NaOH-NA4P207
and dilute H3P04 before conversion to counting gas methane; when noted, marls and lake cores are
treated with acid only. Very calcareous materials are treated with HCL instead of H3P04.
