The Galand-rud coal mine is one of the coal producing areas of central Alborz coal basin which is located in Mazandran Province. Based on mineralogical and geochemical studies pyrite is the main sulfide mineral in the mine. Based on correlation matrix, cluster analysis and principle component analysis (PCA), SiO₂, Al₂O₃, Na₂O, K₂O and TiO₂ are associated with alluminosilicate minerals, CaO, MgO and MnO with carbonate minerals (calcite and dolomite) and Fe₂O₃ and SO₃ with pyrite. Ambiguous correlation between P₂O­₅ and other major oxides and also the presence of apatite in Galand-rud coals indicate two sources for P₂O­₅. A negative correlation between SiO₂, Al₂O₃, Na₂O, K₂O, TiO₂ and Cl indicate organic origin of Cl. Also, V and Rb originate from alluminosilicate minerals, Ni, Cu, Co, Cr, Pb, Ce, Y and Zn from sulfide minerals and Ba, Sr from carbonate and phosphate –bearing minerals. Galand-rud coals enriched in most of trace elements respect to China and America coals and Clark coals, whereas, exhaustion in Cl and Nb.
