摘要： 准噶尔盆地中上三叠统小泉沟群与下伏仓房沟群之间的关系一向被认为是整合连续的。然而,大量资料证明,除盆地南部地区以外,盆地的中北部地区为一大区域分布的不整合,同时下三叠统上仓房沟群也在较大范围内缺失。由于研究思路被传统观念所束缚,该不整合的发现推迟了5年,被普遍确认和肯定则推迟了20多年。莫深1井和石莫1井的钻探使这一问题最终得以彻底解决。

Abstract: The relationship between Xiaoquangou group of the Middle-Upper Triassic and underlying Cangfanggou group of the Lower Triassic in Junggar basin has been considered to be conformable and continuous. However, a great number of information indicate that the central and northern parts of this basin belong to a large unconformity in regional distribution, and the upper Cangfanggou group is absent to a large extent except for the southern area of the basin. The discovery of this unconformity has been delayed 5 years, while the universal confirmation of it has delayed more than 20 years due to restriction of traditional ideas. The key for thoroughly solving this big problem attributes to the drillings of Moshen-1 well and Shimo-1 well.

Key words: Junggar basin, Middle-Upper Triassic, Lower Triassic, contact relation, unconformity, Indosinian movement
