摘要
Maceral composition and aromatic compounds were determined on columnsamples to study the peat-forming environments of Permian coal seam 2 and Carboniferouscoal seam 9^(-2) from the Xingtai coalfield,China.The macerals were dominated by inertinitein seam 2 and by vitrinite in seam 9^(-2).Three maceral groups were selected as indicatorsof peat-forming environments.Two triangle diagrams were drawn based on the indicatorsto explicate the peat-forming environments of permian seam 2 and Carboniferousseam 9^(-2).The results indicate that the peat of carboniferous seam 9^(-2) formed dominantlyin wet swamps,whereas the peat of Permian seam 2 formed dominantly in dry swampsand open moor environments.
Maceral composition and aromatic compounds were determined on column samples to study the peat-forming environments of Permian coal seam 2 and Carboniferous coal seam 9^-2 from the Xingtai coalfield, China. The macerals were dominated by inertinite in seam 2 and by vitrinite in seam 9^-2. Three maceral groups were selected as indicators of peat-forming environments. Two triangle diagrams were drawn based on the indicators to explicate the peat-forming environments of permian seam 2 and Carboniferous seam 9^-2. The results indicate that the peat of carboniferous seam 9^-2 formed dominantly in wet swamps, whereas the peat of Permian seam 2 formed dominantly in dry swamps and open moor environments.
