摘要
本文对塔中29井奥陶系含笔石地层的资料作了分析研究。其含笔石地层的时代属中奥陶世和晚奥陶世早期，大致相当西欧地区卡拉道克（Caradoc）期。含笔石地层层位可与塔中28井和塔北柯坪地区相应的地层层位相对比，大致分别相当于柯坪中奥陶统的其浪─—坎岭组和上奥陶统的印干组。
Based on the analysis and study of poptolite fossil data from well Tazhong 29 in Tdrim Basin, it is considered that the geologic time of the graptolites is Middle Ordovician and early Late Oniovician,approximately corresponding to Caradoc in westem Europe. The Ordovician potolite-bearing strata of well Tazhong 29 may be correlated with the equivalent strata of well Tazhong 28 And Kelping area in the northwesterm margin of Tarim Basin, comeponding to Kanping Formation And Qilang Formahon of Middle Ordovician and Yingan Formation of Upper Ordovician respectively.
