宁夏卫宁盆地晚泥盆世中华豆石介族（介形类）的发现

Discovery of Late Devonian Sinoleperditiini (Ostracoda) in Zhongwei-Zhongning Basin of Ningxia

通过对中华巨石介族的研究，指出宁夏卫宁盆地中宁组下段为法门期滨海相沉积，泥盆纪时属华南生物地理区系。根据生物群和沉积建造的相似性，并结合古地磁资料分析、推测在晚泥盆世期间，包括卫宁盆地在内的河西走廊地体可能还未完全脱离华南地块。

Sinoleperditiini-bearing lower member of Zhongning Formation in the Zhongwei-Zhongning Basin of Ningxia is considered to be Famennian in age and littoral deposits. During the Late Devonian, the Zhongwei-Zhongning Basin may belong to the South China Biogeographical Province because of the presence of Sinoleperditiini there and presumably the Hexi (Gansu) Corridor Terrane including Zhongwei-Zhongning Basin might not yet separated entirely from the South China Block through the analysis of biota (plants,fishes and ostracodes),sedimentary formations and paleomagnetic data from both areas.
