| Abstract: | This paper presents the results of detailed paleomagnetic study on the ophiolite of Danfeng group in Qinling erogenic zone. The paleomagnetic pole position and paleolati-tude of Danfeng group have been located on the basis of the origin and formation age of remanence, as well as the impact of metamorphism and deformation on the characteristic component. The origin and evolution of Danfeng group have also been discussed. |
