Abstract: Abstract: There are a lot of faults in the Kalpin fault uplift. Through field work and interpretation of seismic reflection profiles and Landsat images, the authors consider that the Kalpin Tag fault formed in the Neogene and had a different early evolutionary history from the Shajingzi fault. The Akqi fault formed by compression, rather than by strike slip. The Piqanlik and Yingan strike-slip faults are tear faults that exert concerted effect on the whole zone. In the field, the authors found that the Shargan fault is a false strike-slip fault and in fact should be an out-of-sequence fault. Under compression, two kinds of main fault combination were formed in the Kalpin fault uplift: imbricate thrust sheets and tectonic windows. From an analysis of the main faults in the Kalpin fault uplift, the authors consider that the Cenozoic structures in the Kalpin fault uplift are actually a manifestation of orogeny due to remote collision between the Indian plate and Eurasian plate and intraplate deformation.
