Huge reserves of zeolitic tuff exist in northeast (NEJ), central (CJ), and south (SJ) Jordan. These reserves haven't been studied or evaluated for their mineralogical or geochemical studies. This work focus on the characterization (Thin section, SEM/EDX, X-ray and geochemistry studies) of different location of zeolites in Jordan. Thirty one representative samples were collected from different localities. The samples were investigated for their geochemical and mineralogical composition.
