中文摘要：

新疆维吾尔自治区阿图什市木吉地区邻近帕米尔，是印度板块与欧亚板块碰撞挤压应力最集中的地区，地层变质和变形强烈，研究基础薄弱。木吉群由变质砂岩、板岩、千杖岩、石英岩、钙质石英岩、变粒岩、二云石英片岩、大理岩等组成，一直未发现任何化石。最近，笔者在木吉乡的喀拉足克沟和阿拉木陶沟的粉砂岩、钙质粉砂岩中发现了一些植物管胞片和孢粉化石：Granulatisporitessp．，Cycloranisporitessp．，Verrucosisporitessp．，Pityosporitessp．Punetatosporites sp．，Leiotriletes sp．，Apiculatisporites sp．，Platysaccussp．，Cycodopites sp．等。从地层接触关系和孢粉化石的整体面貌看，木吉地区含上述孢粉化石的木吉群的时代可能为泥盆纪-石炭纪。

英文摘要：

Lying near Pamir, the Muji area, Artux City, Xinjiang, is tectonically located at the junction between the Indian plate and the Eurasian plate, where extrusion stress of plate collision is most concentrated and metamorphism and deformation of strata are strong. Therefore, stratigraphic research is very glancing. The Muji Group is composed of metasandstone, slate, phyllite, quartzite, calcareous quartzite, granulite, two-mica-quartz schist, marble, etc. Fossils have never been reported from this group in the Muji area. Recendy some tracheidal pieces and sporopollen fossils such as Granulatisporites sp., Cycloranisporites sp., Verrucosisporites sp., Pityosporites sp., Punetatosporites sp., Leiotriletes sp., Apiculatisporites sp., Platysaccus sp. and Cycodopites sp. have been found in silt.stone and calcareous silt.stone in the Kalazuke and Alamutao gullies in the Muji area. According to an analysis of the stratigraphic contact relationships and sporopollen features, the age of the Muji Group yielding the above-mentioned sporopollen fossils in the Muji area may be Devonian-Carboniferous.
