摘要
本文对秦岭造山带内丹风群蛇绿岩进行了较为详尽的古地磁研究,通过对剩磁分量成因形成时代及变质变形作用对特征分量的影响的讨论,初步确定了丹风群古地磁极位置和古纬度值,并对丹风群的形成演化作了初步探讨。
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.
