| 摘 要： | 四川盆地下中三叠统嘉陵江组—雷口坡组(T1j-T2L)盐系地层蒸发岩发育,是我国海相碳酸盐岩沉积区探盐找钾的重要地区层位。现通过四川盆地下中三叠统盐系地层古地磁样品的系统采集和测试工作,首次在我国建立了古地磁磁性地层剖面,并根据测定结果,结合地质资料,探索了四川盆地下中三叠统(T1j-T2L)成盐古气候条件及其时代归属等有关问题。

| Abstract: | In the strata of the lower-middle Trias series of Jialingjiang-Leikoupo formations(T_1j-T_2j)in Sichuan Basin,evaporates are extensively located,where forms a significant background for exploring potassium salts.Through systematic collecting and analyzing the palaeomagnetic samples from those strata,the palaeomagnetic stratigraphic profile of for that series was established for the first time.According to the determination results,in combination with geological literature,discussions were made for the salt-forming palaeoclimatic conditions and the attribution of its ages with respect to the series. |
