Local tectonic rotations by paleomagnetic data for Middleupperdevonian effusives of the Volnovakha fault zone
© M.I. Orlova
Results of paleomagnetic studies of the Middleupperdevonian
effusives (390-360 m. y.) have been revised. Statistically well determined directions of typical components
have been turned into stratigraphic coordinate system. Average direction of prefolding component of natural
remanent magnetization: D/l=72°/24°; n=106; a95=2,9°; K=23,07 has been found with the help of magnetization
circles transsection method with corresponding coordinates of virtual geomagnetic
pole F =21,8° n. lat.; Ë=139,1° e. lon. Tectonic rotations of local structures around
vertical axis have been ascertained. <<back |
