The investigations of the isotopic abundance ratios of molybdenum in zircon have shown that the molybdenum isotopic composition obtained reflects two effects: (1) spontaneous fission of 23892U contained in the zircon and (2) double beta decay of 9640Zr. Interestingly, however, the products due to the spontaneous fission appear to have a strange large excess (spike) of 9842Mo. It intrigues us that 92 minus 42 leaves 50, one of the outstanding magic numbers. It is suggested in the present communication that the strange spike of 9842Mo in question can result from a special type of sontaneous fission having essential bearings on the magic number 50 of protons and the "magical" numbers 58 and 92 of neutrons.
