| 摘 要： | 据西藏自治区大地构造演化特征,从整个青藏高原构造单元分布特点考虑,本文将西藏自治区地层区划结合构造单元和含煤地层一并考虑,将其划分为三个构造-地层大区:羌塘-三江构造-地层大区、班公湖-双湖-怒江构造-地层大区、冈底斯-喜马拉雅构造-地层大区。从区域地层、沉积构造及其古生物化石组合等特点综合分析,得出西藏赋煤区聚煤作用具有时代多、分布广、煤层层数多、厚度薄和稳定性差的总体特点。区内含煤地层包括下石炭统、上二叠统、上三叠统、中侏罗统、下白垩统和古近系等。最主要煤系是下石炭统马查拉煤系、上二叠统妥坝煤系、上三叠统土门煤系、下白垩统多尼煤系。

| Abstract: | According to the tectonic evolution of Tibet, from the entire distribution of tectonic units of the Tibetan Plateau to consider, combined Tibet tectonic units subdivision and coal-bearing strata considered together, this paper divided the Tibet into three large Tectonic-stratigraphy areas： Qiangtang-Sanjiang structural-stratigraphic region, Bangong-Shuanghu-Nujiang structural-stratigraphic region, Gangdese-Himalayan structural-strati- graphic region. From Tibet regional stratigraphic sedimentary structure and its characteristics of ancient fossils combination analysis show that the Tibetan coal-rich region coal accumulation process endowed with the multi-eras, widely distributed, multi-layered seams, thin and poor stability of the overall features. District includes the Lower Carboniferous coal-bearing strata, Upper Permian, Upper Triassic, Middle Jurassic, Lower Cretaceous and Paleogene, etc., the main coal-bearing strata are Lower Carboniferous （Machala coal series）, upper Permian （Tuoba coal series）, upper Triassic （Tumen coal series）, lower Cretaceous （Duoni coal series）. |
