| 英文摘要 | Magnetic fabrics of magmatic rocks is usually controlled by magmatic flow and stresses during emplacement and later tectonic alteration. In order to understand the emplacement history of the Fangshan pluton in Beijing, we studied the anisotropy of magnetic susceptibility (AMS) along Dongshankou-Fenghuangting section of the pluton. Thermomagnetic curves and hysteresis loops showed that primary multi-domain (MD) magnetite was dominant. The AMS ellipsoids were characterized as oblate with a high P value (mean 1. 189). From the pluton rim phase at Dongshankou to the central phase at Fenghuangting, the susceptibility ellipsoid E and shape factor T values gradually decreased, suggesting that the magnetic fabrics were formed by magmatic flow and a contemporaneous NNE-SSW direction stress during its emplacement, rather than a post-emplacement tectonic influence. |
