The degree of structural orientation of natural disordered sp2 carbon samples was studied using transmission electron microscopy and Raman spectroscopy. Using both methods, orientation was revealed in two samples, related to the external formation conditions. It was shown that even disordered carbon exhibits elements of structural anisotropy, which should be taken into account when analyzing and applying their physicochemical properties. Keywords: natural disordered carbon, structure orientation, Raman spectroscopy, electron microscopy, image analysis.
