•Systematic investigation of Iranian coal deposit.•Geochemical evaluation of coal deposits for selenium concentration in Iran for first time.
About 478 coal and coaly shale samples were collected to study the selenium content and distribution pattern in Iranian coals in different coal basins. Most Iranian coals have selenium coals lower than 31.5 ppm. The average Se content in Iranian coals is about 1.2 ppm, close to that in the world. The Ksashan coal basin has lowest levels of average Se (0.9 ppm) accumulation. The Se concentration in Iranian coals is influenced by metamorphism and tectonic conditions. The highest concentration of Se in coal-bearing deposits is at Kalishur (31.5 ppm) in Tabas coal basin.
