Three K-Ar ages are presented for glauconites separated from Tertiary sediments at sub Antarctic Sites 280 and 281 of DSDP Leg 29. Glauconite concentrates were prepared at -36 +85 mesh size by magnetic methods. They were then analyzed by X-ray diffraction to check the purity and crystallographic state of the glauconites. The K-Ar analyses were done by standard methods, potassium being analyzed by flame photometry and argon by extraction in vacuo and mass-spectrometric measurement and these results are listed.
