Abstract

Within a reyerite-tobermorite (11 Å) amygdale assemblage in olivine basalt blocks, near Drynock, Skye, is a porcellaneous material which either lines or completely fills the amygdales (Livingstone, 1988). Electron-probe microanalysis combined with back-scattered electron imaging identifies individual components of the porcellaneous material as calcian analcime and bytownite, (An74-79). Back-scattered electron imaging reveals a second generation analcime pervading the calcian analcime-bytownite intergrowth and forming patches and discrete veinlets (Fig. 1A).
