Abstract Two very rare zeolites, boggsite and a tschernichite-type mineral, have been found in the basalts of Mt. Adamson, Terra Victoria Land, Antarctica. Boggsite from Antarctica is chemically characterized by a high Na content in comparison with that of the type locality of Goble, Oregon. Tschernichite-type zeolite is, both morphologically and chemically, quite similar to tschernichite from Goble, but differences in X-ray powder diffraction patterns suggest that the minerals from the two localities have structures which can be described with different polytypic sequences.
