Coals from fourteen Bulgarian basins and deposits were sampled. The siderophile elements Fe, Ni, Co, Mn, Cr, V, Ti and their distribution were studied in these samples. The coals have different rank and age. The studied lignite was taken from the Neo

The lignite seam from the Sofia Neogene basin has been sampled and the petrographical composition was determined. The coals contain high contents of macerals from the huminite group. The prevailing macerals from that group were textinite, ulminite an

Petrographic analyses of 137 Bulgarian coal samples collected from an underground mine in the Oranovo–Simitli basin show vitrinite (huminite) reflectance values near 0.34%. This middle Miocene age coal is mostly made of vitrinite (huminite), with a

The Carboniferous succession in the Donets Basin hosts about 130 seams, each with a thickness over 0.45 m. Nine economically important seams from the (south)western Donets Basin are studied using organic petrographical, inorganic geochemical, and org

Twenty-five minerals were established in the coal from Oranovo-Simitli basin. More of them were silicates. The sulfide minerals were less than the silicates. All other minerals were oxides, sulphates and phosphates, which were presented, in small amo

The Katrishte lignite deposit is located in southwest Bulgaria. A new, open pit deposit, it is characterized by high concentrations of Si, Al, Fe, Ni, As, Co, Cd, and Mo. The distribution of these elements is related to the ash content in the coal se

Lignite samples from the Balsha seam in the Sofia Neogene Basin were collected and ashed. The coal ash was analysed for major and trace element contents. The concentration of most of the elements in the coal ash was higher than the Clarke value: Ag,

The occurrence and distribution of Сu, Zn, As, Мо, Ag, Sn and Рb was investigated in coals of various rank (ranging frоm lignite to anthracite) frоm thirteen coal basins in Bulgaria. The concentrations of almost all elements in the coal ash and
