内容記述 |
The isothermal remanent magnetization (IRM), J_R(H_+H_0), the shock remanent magnetization (SRM), J_R(H_+SH_0), and IRM with an advance shock, J_R(SH_+H_0), acquired in a magnetic field H and with a shock momentum S, are experimentally examined for two stony meteorites, Yamato-75097 L4 chondrite and Jilin H chondrite. Just as in the case of terrestrial igneous rocks, stony meteorites can acquire the characteristic magnetizations in a small magnetic field and with a large value of S in such forms as expressed by J_R(H_+SH_0)≃KSH>J_R(H_+H_0) and J_R(SH_+H_0)≃FSH>J_R(H_+H_0), where F≃(1/3)K. If we assume that a stony meteorite is impacted by a mechanical shock of P in maximum compressive shock pressure in non-magnetic extraterrestrial space and then enters the geomagnetic field of 0.5 Oe, P is estimated to be 3 kbars and 0.63 kbars for the Jilin and the Yamato-75097 respectively. Both the chondrites have the same anisotropic characteristics of J_R(H_+H_0), J_R(H_+SH_0) and J_R(SH_+H_0) as their magnetic susceptibility. |
