摘要
本文根据塔里木盆地群克1井和草湖1井采集的笔石标本作了分析研究:群克1井所含笔石地层的地质时代属晚奥陶世,相当西欧阿什基尔(Ashgill)期;草湖1井所含笔石的地质时代属早志留世早期,相当西欧兰多维利(Llandovery)早期。它们所含笔石地层的层位,可与塔里木盆地西北缘柯坪地区的相应地层层位作对比,分别大致相当于下柯坪塔格组和上柯坪塔格组。
This paper deals with the graptolite-bearing strata of the Qk-1 and C-1 wells in Tarim Basin.The geological age of the graptolites collected from the well OK-1belongs to the Late Ordovician,and that from the well C-1 belongs to the early Early silurian。 The graptolite-bearing strata mentioned above may be correlated with those of Kelping mountains of the northwestern margin of Tarim Basin, approximattely corresponding to the Lower Kelpingtag Formation and the Upper KelpingtagPormation separately.
