鲁西南地区石炭二叠纪煤的热演化史研究

本文应用洛帕金～韦甫斯法对鲁西南地区构造史、沉积埋藏史和石炭二叠纪煤层的热演化史作了三位一体的详细研究,提出了煤系形成后经历了四次构造演化阶段,建立了三种沉积埋藏模式,并依次恢复了其古地温,最后,在建立地质模型和温度模型的基础上,论述了煤的变质演化,得出了煤变质的三个演化时期和各个煤质分区的主要增进期.

Thermal evolution history study of coal in Southwest Shandong Carboniferous-Permian coalfield

With the N. V. Lopatin -D. W. Waples Method, detailed studies are conducted of the arthi-tectonic history, sedimentational history and thermal evolution history of the Carboniferous-per-nian coal seams. A proposal is made about four arthitectonic evolution stages after the coal series, and the three depositional models established. On the basis of the geological models and temperature models established, the metaphoric evolution of coals is expounded, which is supposed to cover three stages with a major enhancement period each. Finally, a discussion is made about the coal quality distributional patterns in the region of Southwest Shandong.
