摘要
色日巴彦敖包组为2006～2008年内蒙古自治区地质调查院在扎鲁特旗地区进行1∶5万区域地质调查时新识别出来的地层单位.在该组下部灰黑色凝灰质粉砂质硅泥质板岩中发现早石炭世古植物化石Archaeocalamites sp.(古芦木).根据岩石地层对比及生物化石特征,将其时代由早二叠世归为晚泥盆世—早石炭世,并重新厘定为色日巴彦敖包组.
During the 1：50000 regional geological survey in Jarud Qi from 2006 to 2008, the Early Carboniferous fossil plant of Archaeocalamites sp. was obtained from the gray-black silty tuffaceous silicon-pelitic slate in the lower part of the formation. Its age had been originally considered as the Early Permian. Based on the stratigraphic correlation and paleontological characteristics, the formation that includes plant fossils of Archaeocalamites sp. is revised as Late Devonian- Early Carboniferous, and assigned to Seribayanaobao Formation.
