| 摘 要： | 本文详细探讨了河南省下二叠统山西组二_1煤中硫的分布规律、赋存状态及成因,指出煤中硫的含量主要受泥炭沼泽介质性质和成煤植物的控制。当介质为半咸水时最易形成高黄铁矿硫煤,淡水介质时往往形成低黄铁矿硫煤。煤中有机硫的含量主要受成煤植物控制,当成煤植物为辉木类时易形成高有机硫煤:以石松类为主时,有机硫含量极低。最后从微生物地球化学角度论述了煤中黄铁矿的形成机制,建立了煤中黄铁矿的成因模式。

| Abstract: | In this paper, the distribution, occurrence and qrigin of sulfur in Ⅱ. coal of shanxi formation (Lower Permian) in Henan provicc will be elaboratcd. The content of sulfur in Ⅱ, coal is controlled by the medium of pcat swamp and coal forming plants. High pyritic sulfur is formed under saline medium, and low pyritic undcr fresh. The qrganic sulfur in Ⅱ, coal mainly comes from coal forming plants. The qrganic sulfur in Ⅱ, coal which is formcd from Psaronius is higher than that from Lycopsid. Based on the microbiogrochcmistry. the mechanism of pyritic formation in Ⅱ, coal. can bc explained thoroughly, and the model of pyritic formation can be established. |
