| 摘 要： | 内蒙古东部黄哈吐地区1∶5万区调工作,在前人划分的"大石寨组"中,新发现了一套走向NE的地层,岩石组合为粗火山碎屑沉积岩夹微晶灰岩及中性火山碎屑岩,内含丰富的腕足、珊瑚、苔藓虫等化石.时代属于中泥盆世早期,大体相当于艾菲尔阶-吉维特阶,应归属为大民山组.由于该套地层在黄哈吐地区为首次发现,对大地构造及地层区划等基础地质的研究有着重要意义.

| Abstract: | During the regional geological survey with 1/50000 scale, Devonian-System that was regarded as the Da-Shi-zai Formation of Lower Permian series have been discovered in Huang-Hetu area of the eastern of Inner Mongolia. The strata strike NE, and its rock association are consisted of pyroclastic sedimentary rock, micrite and pyroclastic rocks, and containts brachiopoda, coral, bryozoan. The geochronologic unit is belonged to Early Age of Middle Devonian Epoch, and correspond to Eifelicus Stage-Jiweite Stage, and is belonged to Daminshan Formation of Devonian system. The strata discovered firstly in Huang-Hetu area are of indicative significance for basic research, such as division of geotectonics and strata. |
