Geochemical properties of coals in the Lushan coalfield of Iran

A preliminary study of mineralogy and geochemistry of four coal samples from northern Iran

“…Yazdi and Shiravani (2004) have recently reported major oxide, Mn, Sr, V, and Zn concentrations from the Lushan coalfield of northern Iran. The Iranian Steel Corporation also carried out an extensive study of Iranian coals as related to their coking properties (Razavi-Armagani and Moenoalsadat, 1994;Shariat Nia, 1994).…”

Geochemical and environmental baseline of major and trace elements in Zarand coals, southeastern Iran

“…However, the Au, Pd and Pt concentrations in Zarand coal tailings are 0.015, 0.012 and 0.02 mg/kg, respectively. Yazdi and Esmaeilnia (2003), Yazdi and Esmaeilnia (2004) and Yazdi (2012) reported very high gold values (0.311, 311 and 13 mg/kg or ppm) from Shahroud and Lushan coal mines, northern and western Alborz basin coal deposits, and northern coalfields of Iran. As the authors did not mention any precision or accuracy for the questionable erratic high gold contents, further studies and revisions are required for new data of gold in Shahroud and Lushan coals.…”

Petrology, rank and evidence for petroleum generation, Upper Triassic to Middle Jurassic coals, Central Alborz Region, Northern Iran

“…Some coals in central Alborz region are reported to have b 10-50% ash, and sulphur and phosphorus ranging from 1.1% to N 5% and b0.01% to N 0.1%, respectively (Razavi-Armagani and Moenoalsadat, 1994) although Goodarzi et al (in press) recently showed that the coals from Glanddeh-Rud, Gajereh, Shemshank, and Zerab have between 0.34% and 0.69% total sulphur (0-0.115 wt.% pyritic) and ash contents of 1.36 to 20.97 wt.%. The inorganic geochemistry and selected trace element composition of Alborz coals are reported on elsewhere by Yazdi and Shiravani (2004), and Goodarzi et al (in press).…”
