A brief report about geological history of Zeolites present in different localities of Ethiopia is presented. Scanning electron microscopy (SEM) was used to study the habit and surface topography of the samples collected in the rift valley region, Nazert (Ethiopia). Data collected from this studies carried out on the samples is presented. SEM micrographs of needle shape and elongated rod-like crystals are illustrated. Through chemical analysis, the samples are identified as Gismondine. A possible mechanism of growth and formation of various shapes of these natural Zeolites is proposed. Important industrial and agriculture applications of Zeolites are given. Future scope in this field is also explored.
