摘　　要：西秦岭武山杨河—礼县固城—带的原“泥盆纪”地层中,发现了大量属于早石炭世的牙形刺、珊瑚和有孔虫化石,为该区地层的重新划分提供了直接的证据。这对于重新认识该区乃至整个西秦岭地区石炭纪古地理格局、地质演化历史、沉积相和沉积环境等都有重要的意义。The authors have discovered many fossil conodonts, corals and foraminiferas of the Lower Carboniferous from the so-called Devonian strata in Yanghe, Wushan and Gucheng, Lixian of the western Qinling, which provides direct evidence for redivision of those strata. It is of most crucial significance to a new understanding of the Carboniferous palaeogeographical setting, the evolutionary history and the sedimentary environment of this area, as well as of the whole western Qinling.
