Abstract

Abstract The sample of portite studied by D'Achiardi (1873), a fragment of the holotype of Meneghini & Bechi (1852), was rediscovered in some of the oldest collections of the Natural History Museum of Pisa University. X-ray and optical data demonstrate that portite is identical to natrolite, thus allowing us to discredit the mineral name portite. This proposal is approved by the I.M.A. Commission on New Minerals and Mineral Names. Moreover, X-ray data show "schneiderite" to be identical to laumontite.
