A relatively rare zeolite, Faujasite was first discovered in 1842 in Kaiserstuhl, Germany (Damour, 1842). A number of other vesicle-filling occurrences are known. In the sedimentary environment, Faujasite has been recorded from only two localities (Gottardi & Galli, 1985); in palagonite tuff from Oahu, Hawaii (Iijima & Harada, 1969), and in palagonitized basaltic glass from Southeastern California (Wise, 1982). Faujasite occurrences in these areas are not economically feasible. New localities were discovered and described for the first time in Northeast Jordan in 1995. Preliminary evaluation of the Faujasite deposits in Jordan has revealed their economic importance. Further investigation and analysis of its feasibility showed that Jordan has the only source of natural Faujasite in commercial quantities in the World.
