A rare earth-containing zeolite with a cocrystalline structure of ZSM-5 and ZSM-11, wherein the weight ratio of the moiety having the crystalline structure of ZSM-5 to the moiety having the crystalline structure of ZSM-11 is 0.1 to 10, which has, in the sodium form, the X-ray diffraction pattern set forth in Table 1, and in its originally synthesized anhydrous state, a chemical formula in terms of mole ratios of oxides as follows: 0.1-1.0 Na.sub.2 O.0.01-1.0 RE.sub.2 O.sub.3.Al.sub.2 O.sub.3.20-300 SiO.sub.2. Said zeolite has good acid hydrothermal stability and resistance against impurity contamination, and is useful as catalyst in various hydrocarbon conversions.
