摘要
The depth to detachment level is a critical factor affecting the quality of structural modeling in fold and thrust belts. There are several detachment levels developed in the Kuqa depression. Based on the excess-area diagram, this paper concerns mainly the calculation of the depth to detachment in the Kuqa depression. The result demonstrates that the detachment levels are situated in different strata in varying zones, such as the Paleogene Kugeliemu Formation, the Paleozoic and the crystalline basement. The calculated depth to detachment level is very helpful for testing whether a structural interpretation is reasonable and for defining the depth of deeper detachment levels which were not discerned in seismic profiles.
