Abstract—The concentration and distribution of germanium in coals from the Spetsugli section of the Pavlovsk brown coal deposit in Primorskii krai was studied using mass spectrometry and laser microanalysis. The maximum concentrations of germanium in low-ash coals were established. The distribution of germanium in the vitrinite group macerals of coals and in mineral impurities was studied. A conclusion on the accumulation of germanium in coals at the stage of ancient peat accumulation was made.
Keywords: germanium, concentration, element, mass spectrometry, laser microanalysis
