Abstract

SUBSEQUENT to the publication1,2 of potassium/argon dates from basement rocks of the McMurdo Sound area, a few additional dates have been obtained. As shown in Table 1, the potassium/argon dates now available represent a variety of igneous and metamorphic rock types. Each reported date is based on an average of two or three determinations of radiogenic argon content.
