| 7. | Dongtujinhe formation first been established in yining minor strata area , not only have an important value in stratigraphic correlation , but also proves that the yining basin similar as boluohuoluoshan blok in sedimentation and evolutionary process 东图津河组在特克斯盆地的首次确立,具有重要的地层对比意义,至少说明在晚石炭世伊犁盆地与博罗霍洛山地块具有相同的沉积作用及其构造演化特征。 |
| 8. | Linnan sub - depression which is mesozoic and cenozoic faulted lacustrine basin is located in the southwestern part of huimin sag , depression of jiyang . it is dominated by lacustrine - fill sub - depression . based on well logs , three - dimension seismic profiles , cores and other basic data , 10 horizons including 6 turnaround surfaces and 4 maximum flooding surfaces are defined from es3 to the lower part of es2 formation , and 1 long - term and 5 intermediate - term base - level cycles which are named from c5 to c1 could be identified , and then the chronostratigraphic framework of the sub - depression is built 本文以岩心、钻井、测井、地震资料为基础,在下第三系沙三段沙二下的一个长期基准面旋回(二级层序)内部识别出10个有时间地层对比意义的界面,包括6个基准面下降到上升的转换面(层序界面) , 4个基准面上升到下降的转换面(湖泛面) ,划分出c1 - c5五个中期基准面旋回,建立了等时地层格架地层格架。 |
| 9. | They contain rich volcanic rocks and minerals by which reliable iso - chronic data can be got , possess successive sandstone and mudstone by which accurate magneto - stratigraphic columns can be set up and distinguish geological events , and also contain a large number of wide - spread fossils which can be used to correlate strata in a large scope 与海相地层比较,陆相地层在同位素测年、磁性地层划分和事件地层学研究方面具备建立层型的优势,同样可以找到分布广泛和利于大范围地层对比的化石门类。 |
| 10. | On the basis of the work on this area of many scholars " , according to the correlation principles which are from the big orders to the small orders , from the shallow outcrops to the deep burial area , from the southern marine formations to the northern continental formations , a sequence stratigraphic framework is set up with different orders 在前人工作的基础上,遵循先大后小的原则,采取从浅部露头到深部埋藏区的对比,从南向北从海相层向陆相地层对比的方法,建立了不同级别的等时地层格架。 |
