| 摘 要： | 磁组构是指磁化率的各向异性。北京崎峰茶－琉璃庙地区岩石磁组构造特征是磁各向异性度Ｐ值、磁椭球扁率Ｅ＞０为主、磁面理发育而磁线理很差。本区构造变形强烈，以压扁变形为主，Ｓ－Ｎ向构造带是东盘上升、西盘下降，Ｅ－Ｗ向构造带是上盘由南向北逆冲。

| Abstract: | The magnetic fabric means the anisotropy of the susceptibility. The characteristics of the rock magnetic fabric in Qifengcha Liulimiao area are that the value of P which symbolizes the degree of the magnetic anisotropy is high, the value of E symbolizing the ellipsoidel flattening is above zero, the magnetic schistosity is well developed and the magnetic lineation is poor. The analytical results of the magnetic fabric show that the regional structural deformation is strong, of which the flaser deformation is the chief, the west side of the NS trending structural zone moved down with respect to the east side and the hanging wall of the WE trending structural zone thrusted up with respect to the foot wall from south to north. |
