In order to efficiently extract quantitative parameters in active tectonics research, JX4C digital photogrammetric system has been used to found stereo model based on CORONA KH-4B stereo pairs with 2 m resolution, which were declassified in 1995 by USA for scientific purpose. These processing techniques are applied in a case study of the Kuqa fold-and-thrust belt in southern Tianshan, China, to quantitatively analyze the Kumugeliemu active fault and the Qiulitage active fault-related folds, considering the seismic reflection profiles therein and data from field measurements. Results show that the CORONA stereo pairs can be used in JX4C digital photogrammetric system, and root mean square error (RMS) of relative orientation is about 0.01 mm, while absolute orientation is about 10 m.
