A suitable technique was developed for preparation of lignite ash deposits for electron microprobe examination. Prepared samples were analyzed for concentrations and distribution relationships of seven elements at four separate positions in the bulk deposit. Forty-two discrete groups of these elements were identified, each of which may represent more than one chemical compound.
