舞阳含盐盆地位于河南省叶县及舞阳县境内,面积约1900km~2。石油部南阳油田在本区开展找油工作时,在石油钻井中发现了厚层石盐岩。舞阳含盐盆地是周口坳陷西南部的一个次级构造单元。周口坳陷横跨豫东、皖西,面积约3.2万km~2;大地构造位置为华北地台的南缘,秦岭褶皱系的北侧,是华北坳陷区最南部的一个坳陷。舞阳含盐盆地的含盐层赋存于下第三系核桃园组的中上部,该组与江汉盆地的潜江组、大汶口盆地的官庄组中段及东营盆地的沙河街组沙四段层位相当,基本属于下第三系
Wuyang salt basin is located in Ye County and Wuyang County, Henan Province, an area of about 1900km ~ 2. Nanyang Oilfield Oilfield in the area to find oil work, found in the oil drilling thick rock salt rock. Wuyang salt basin is a secondary tectonic unit in the southwestern part of Zhoukou Depression. The Zhoukou Depression traverses the eastern part of Henan Province and the western part of Anhui Province, covering an area of about 32,000 km ~ 2. The tectonic location is the southern margin of the North China platform and to the north of the Qinling fold system is a depression in the southern part of the North China depression. The salt-bearing strata in the Wuyang salt basins occur in the upper-middle part of the Lower Tertiary Hetaoyuan Formation, and are similar to those of the Qianjiang Formation in the Jianghan Basin, the middle part of the Guanzhuang Formation in the Dawenkou Basin and the Shahejie Formation in the Dongying Basin Segment of the same level, the basic belongs to the next Tertiary
