Abstract (in english)
   According to the cryptovolcanic hypothesis, tectite parent craters are products of hyperexplosive volcanism of stabilized Earth crust. Together with other so-called astroblemes, they belong to the alnöite-kimberlite-carbonatite-cryptonatite-cryptovolcanic structures association, which is genetically related to deep-seated faults. Published but neglected data demonstrate the repeatedly-acting nature of tectite parent structures and a multiphase, long term evolution of their breccias. An additional problem is that the genesis of bottle-green microtectites and high-Na Australian tectites and the zonality of tectite strewn fields are incompatible with the impact hypothesis
