| 摘 要： | 黑鹰山地区下泥盆统上部发育一套巨厚的碎屑岩夹火山岩、碳酸盐岩沉积，划分为清河沟组，其中含腕足类化石２０余属，以厚壳的石燕族和大型扭月贝族占优势，以Ｐａｒａｓｐｉｒｉｆｅｒ一Ｒｈｙｔｉｓｔｒｏｐｈｉａ为组合代表，它们均生活于高能近岸浅海环境。本区腕足动物群与新疆北部、内蒙古及大、小兴安岭颇接近，与哈萨克斯坦以及俄罗斯的萨彦一阿尔泰、远东等地亲缘关系密切。故本区早泥盆世晚期腕足动物地理区应属老世界域的中国北方区。文中补遗描述部分腕足类属种。

| Abstract: | A series of hugely thick clasolite in te rcalated with volcanic rock and carbonatite is developedHeiyingshan area in the up side of the bower Devonian,It is divided into Qinghegou Formation and inwhich is bering more than 20 genera of brachiopod. The dominant element is marked by spiriferoidsand big strophomenoids that is represented by Paraspirifer-Rhytistrophia Assemblage.They show a cur-rent activity,near-shore,shallow water environment.The brachiopod fauna of Heiyingshan area is similar to that of North of Xinjiang,Nei Mongol,DaHingan Ling MTS and Xiao Hingan Ling MTS.It has a close affinity fo Kazakh-stan,sayanAltai and Far East of Russin etc. Thus,this area shOuld belong to North China Region(otprovince )of the Old World Realm in respoct to reginalism of brachiopod zoogeography during lateEaly Devonian time.The part brachiopod genera and species are described as addendum in this paper. |
