| 英文摘要 | This paper studies magnetic properties and composition of granulite-facies rocks of both the Neogene and Archean continental lower crust in the Neogene xenolith-bearing Hannuoba () alkaline basalt and the exposed lower crustal section in the Archean Huai'an terrain (Wayaokou ()-Manjinggou () profile), the northern North China Craton. It provides a unique opportunity for a comparative study of magnetic properties and composition of both the Archean and Neogene continental lower crust. We measure magnetic parameters (susceptibility x and magnetic hysteresis parameters, such as saturation magnetization J(s), saturation isothermal remanent magnetization J(rs) and intrinsic coercivity H-c) of eleven Hannuoba lower Crustal xenoliths and nine terrain granulites from the Archean Huai'an terrain. Results indicate that the average values of kappa, J(s) and J(rs), of Archean granulites are 4 122x10(-6) SI, 523.1 A/m and 74.9 A/m, respectively, which are generally higher than those of granulite-facies xenoliths (1 657x10(-6) SI, 163.9 A/m and 41.9 Aim, respectively). These two types of granulites contain ilmenite, (titano) magnetite, minor hematite and some "magnetic silicates" (clinopyroxene, plagioclase and biotite). The Mg-rich ilmenite in granulite-facies xenolith is relatively higher than that in terrain granulites. We observe a more evolved character as higher magnetic as well as lower Sr/Nd, Cr/Nd, Ni/Nd, Co/Nd and V/Nd ratios in terrain granulites. These differences in magnetic characteristics reflect their different origins and evolutions. The high magnetization of granulites in the Huai'an terrain represents magnetic properties of the Archean continental lower crust, and low magnetization of granulite-facies xenoliths represents magnetic properties of the Cenozoic lower crusts in the northern North China Craton. |
