A sample population of 100 spherules from the area of the Tunguska event of 1908 was examined by SEM techniques. According to their morphological features, the spherules are subdivided into several types: compact, rough, regolith-like, mosaic, and 'astrakhan-coated.' Any hypothetical link between the Tunguska body andd spherule morphology requires the body to be capable of converting its evaporated debris into spherules resembling ablation products of iron meteorites.
