| 摘 要： | 通过对东濮凹陷盐岩及火山岩的研究发现,虽然火山岩分布在凹陷南部,盐岩分布在凹陷北部,但它们的发育层位一致,具有等时异相的特征.结合东濮凹陷构造及演化特征分析认为:古近系盆地的不断伸展引发了火山活动,火山作用导致湖水咸化,密度大的盐水下沉,在湖底形成高密度热卤水;受南高北低古地形影响高密度热卤水自南向北流动,随着温度的降...

| Abstract: | By studying volcanic and saline rocks in Dongpu Depression,it was found out that they had features of equitime and heteropic facies,although volcanic rocks were distributed in the south,while saline rocks were distributed in the north.Based on the analysis of tectonic evolutional characters in Dongpu Depression,it was considered that volcanism was caused continuously in the Paleaogene basin,it induced lake water saline,dense lake water sunk onto the lake bottom and created hot brine with high density.Heavy ... |
