Many unexplained phenomena associated with the radioactive halos in very old minerals are described in the literature. In this paper these phenomena are enumerated. The new hypothesis that a primordial superheavy element (SHE) survived in the earth"s crust can help to solve the problems. According to this hypothesis, the SHE decays by spontaneous fission into fragments of very different mass. The heavy fragments, assumed to lie in the region of the natural decay series, exhibit many indications for a SHE. Additionally, the alpha decay of SHE may occur. Applying the methods of mass spectrometry and X-ray fluorescence can probably prove the existence of SHE.
