Two samples of natural glass from the collection of Academician N. P. Yushkin, presumably attributed to tektites of the Austalasian scattering field, were characterized by chemical analysis, electron microscopy, infrared, 57Fe Mossbauer spectroscopy, and electron paramagnetic resonance. According to the research results, both samples have typical characteristics of the Australasian tektites of the Indochinese flank (Indochinites). The samples differ well in chemical composition and spectroscopic characteristics, the degree of polymerization of the aluminosilicate framework, and the structural positions of iron ions. The difference is related to the disparate fields within the same region.
