河西走廊西段及邻区早白垩世盆地的重新厘定
|
摘要
对河西走廊西段及邻区的地震剖面进行了解释 ,结合钻井资料对其早白垩世时期的沉积与构造特征进行了系统分析 ,对盆地的原型进行了新的厘定。在早白垩世时期 ,该区中部并未发育宽台山 黑山隆起与天泉寺 合黎山隆起 ,原酒西盆地与花海、酒东和金塔盆地应同属统一的酒泉盆地。其中 ,原花海、酒西盆地应同属统一的酒西坳陷 ,内含青西、赤金、石大 花海 3个凹陷 ,后者又可以进一步分为花海次凹、石北次凹和大红圈次凹。原金塔、酒东盆地应同属统一的酒东坳陷 ,内含金塔、盐池、营尔和马营 4个凹陷。 2个大坳陷间以嘉峪关隆起作为分隔 ,而原始盆地的南部边界应位于现今边界以南 3 0～ 5 0km处。
The seismic profile sections and well data of the western Gansu corridor and nearby regions were analyzed. The sedimentary and structural characteristics of the early Cretaceous basins in this area were investigated. A new prototype of basins developed in the early Cretaceous was proposed. It is pointed out that the formerly named as Jiuxi, Huahai, Jiudong and Jinta basins actually belong to one large basin named as Jiuquan Basin now, because the central Kuantaishan-Heishan Uplift and Tianquansi-Helishan Uplift were not developed in the early Cretaceous. The former Huahai Basin and Jiuxi Basin actually belong to a large depression named as Jiuxi Depression composed of Qingxi Sag, Chijin Sag and Shida-Huahai Sag. The later sag is composed of Huahai Sub-Sag,Shibei Sub-Sag and Dahongquan Sub-Sag,and the former Jinta Basin and Jiudong Basin are actually made up of another large depression named as Jiudong Depression including Jinta Sag, Yanchi Sag, Yinger Sag and Maying Sag. The two large depressions are separated by the Jiayuguan uplift, Which is a south-north extending uplift between the two depressions. The southern boundary of the large basin in the early Cretaceous is on the northern Qilianshan and has a distance from 30 to 50 kilometers to the boundary of the present basin.
