| 摘 要： | 陕西小秦岭地区太华群变质岩与国内外许多高级片麻岩区类似，存在大量的深成花岗质片麻岩体，它们经过多期变质变形作用，形成具不同基础岩石类型的多相片麻岩。本文在吸收前人研究成果的基础上，依据区内岩石组合的岩石学、岩石地球化学等特征，将原划太华群重新厘定为太华岩群、翁岔铺片麻岩套、太峪岭片麻岩套、佛头崖单元、罗斑花岗伟晶岩及葫芦沟变砂岩，并首次在本区建立了相应的构─岩石单位体系。

| Abstract: | There is the similarity between the metamorphic rock in Tai Hua group and the gnesis with high degree at home and abroad. There are many plutonic granite-gnesis in this group which has undergone poly-metamorphic deformation. According to the characteristics of petrology and lithogeochemistry, the Tai Hua group insted of Tai Hua group, is established,which consists of Weng Cha Pu gneiss suit, Tai Yu Ling gneiss suit, Fo Tou Ya unit, Luo Ban granite pegmatite and Hu Lou Gou metasandrock. The tectonic-rock unit system is put forward in this area. |
