Study on marine transgression of Paleogene Shahejie Formation in Jiyang Depression;
济阳坳陷古近系沙河街组海侵问题研究
The Donghe Sandstone was broadly deposited in the early stage of the marine transgression,but it is not an isochronous stratigraphic unit.
东河砂岩是一套覆盖广泛的海侵初期的沉积产物,但不是一个等时沉积体,相当于晚泥盆世晚期至早石炭世早期沉积,具体沉积时间各地有差异。
Whether there was marine transgression in Dongpu depression influences the evaluation of its oil gas resource.
东濮凹陷是否有海侵发生 ,直接影响着油气资源的评价 。
The high concentration regions were coupled with marine invasion ranges in the Holocene,indicating the fluorine pollution was cau.
高氟含量区分布与全新世海侵范围基本一致,两者具有较好的耦合关系,表明该区氟元素污染属于自然作用引起的土壤污染,与人类经济活动关系不大,推测这是由于海水中氟元素在土壤富集的结果,需要采取相应措施进行土壤中氟元素污染的回避、防治和修复。

The sea transgression in the interglacial periods provided the water source for formating the subsurface brine,the climatic fluctuations created the conditions for seawater concentration,and the sea regression in the glacial periods made the terrigenous meterial cover the marine deposites so as to conserve the subsurface brines.
间冰期的海侵提供了形成地下卤水的水源,气候波动产生了海水浓缩的条件,而冰期海退过程中,陆源物质覆盖于海相沉积上,保存了地下卤水。
By characteristic analysis of strontium and sulfur isotopes in the studied area,it was discussed whether the transgression has happened in Paleogene in the Jiyang depression.
