Scientific paper

An electron microscope was used in an investigation which compared the surface structures of irghizites from the Zhamanshin crater in Kazachstan, USSR, with those of such typical tektites as australites and pyroclastics such as obsidians and lapilli. The results indicate no unambiguous genetic relationships between irghizite morphology and tektite and pyroclastic surface features. Irghizite surfaces instead result from simultaneous or successive processes in the course of which variously-dimensioned globules melted, fused and were eaten into by corrosive gases after solidification. The assumption that the verrucose glass globule swellings, which are identical in chemical composition to the glass bulk of the irghizites, were caused by expanding glass bubbles immediately below the glass bulk surface may be discounted.
