皖南地区广泛分布着溪口群浅变质岩地层，尽管对其进行了大量的研究，但关于地层时代的归属问题仍存在很大争议。在皖南溪口群采集的43件样品中发现较丰富的陆生植物孢子（Spoers）20余属，50余种，其中具有地层意义的孢子有15属25种。这些孢子组合可与中国华南、西南、西北地区及新疆塔里木盆地巴楚地区晚泥盆世晚期孢子带相比较，也可与西欧、东欧和北美地区晚泥盆世法门阶（Famennian）孢子带对比，其时代为晚泥盆世晚期，相当于西欧晚盆世晚期法门阶（Famennian）。

The epimetamorphic rocks of Xikou Group is extensively exposed in southern Anhui Province, but their age remains a problem of much controversy in spite of much work done. The present work was based on collective and extensive studies of Late Devonian spores (15 genus, 25 species) found in various areas of southern Anhui. The composition of the spores assemblage from the epimetamorphic rocks was discussed and the value of the assemblage for stratigraphic correlation was assessed. The authors made direct comparisons of the epimetamorphic spore assemblage with assemblages of similar Late Devonian ages from south, southwest, and west Tarim Basin, and also with those from the late Late Devonian spore zones in Western Europe, Russia and North America. It is concluded that the age of the spore assemblage is late Late Devonian, equivalent to the late Famennian of Western Europe.
