Abstract

This study focuses on geological and petrographical properties of BITUMINOUS coals (82% 10Ra) of Galanderud region of central Elburz in northern Iran. Coals of this region within coaly sediments of the SHEMSHAK Formation with the age of the Upper Triassic–Lower Jurassic have been deposited in the form of 32 coal beds. These coals are characterized by a relatively high percentage of ash (12.2-18.6%), volatile matters (28.3-39.3%) and calorific value (7430-8880 kcal/kg). The total sulphur amount of Galanderud coals is low (0.45-1.05 %wt), which indicates that the coals of this region have been deposited in fresh water limnic sedimentary environment. Detected minerals in Galanderud coals are dolomite (more than 80%), siderite, quartz, sphalerite, galenite and kaolinite, and pyrite mineral is seen only in the form of fine within coals of coal layers. MACERALs, forming organic part of these coals are mostly of vitrinite (collotelinite) and inertinite (fusinite) group, in which the pores and fissures have been filled with carbonate and silica. As the percentage of coal's volatile matters decreases from surface layers toward the bottom, the RANK of the coals increases and coal types change from gas to pity gas.
