库车坳陷位于塔里木板块和南天山造山带的过渡部位,内部构造较为复杂,中部普遍发育厚度及岩性变化较大、塑性较强的两套膏盐岩。针对库车地区多滑脱层发育的特点,在深化克拉苏构造带盐构造建模的同时,充分考虑煤系滑脱层的作用,提出克深构造带受膏盐岩和煤系地层共同控制的双滑脱层构造解释模式,建立了典型剖面的地质解释模型。这一举措改变了对中生界基底断层和构造样式的认识,由基底卷入构造转变为受侏罗系煤系地层控制的滑脱逆冲构造,研究人员对双滑脱构造发育特征进行进一步的具有针对性的研究,并得到了克深2区块三维地震资料的证实,从而进一步明确了该区中生界断裂发育及构造变形机制,构造模式及断裂系统认识更加合理,使得双滑脱构造建模技术渐趋完善。
The Kuqa Depression is located at the transitional part between the Tarim plate and the South Tianshan orogen. The internal structure is rather complicated. Two sets of gypsum salt rocks with large changes in thickness and lithology and strong plasticity are generally developed in the central area. In view of the characteristics of multi-slip delamination in Kuche region, the model of salt structure in Kelasu tectonic belt is deepened, while the effect of coal-bearing slip layer is taken into full consideration. Slipping layer structure interpretation model, established a typical section of the geological interpretation model. This move changed the understanding of the Mesozoic basal faults and tectonic styles from basal intrusive structures to slip-thrust structures controlled by the Jurassic coal-bearing strata. The researchers further characterized the developmental features of the double slip structures, And the confirmation of the three-dimensional seismic data of Block 2 in Kenshen area, which further clarifies the understanding of Mesozoic fault development and tectonic deformation mechanism, tectonic mode and fault system in this area and makes the model of double slip structure Technology is getting better.
