| 摘 要： | 目的为确定小秦岭地区发育的变质杂岩体是否属于变质核杂岩。方法总结前人归纳的变质核杂岩特征,与小秦岭地区发育的太华杂岩特征进行对比,再通过对小秦岭地区燕山期后褶皱、南北两侧发育的断裂进行分析和构造演化史研究。结果小秦岭地区的构造特征与变质核杂岩特征不符。结论小秦岭地区的太华杂岩解释为经历了从南向北的铲状逆冲推覆和后期抬升块断剥露的变质杂岩更为合理。

| Abstract: | Aim In order to determine whether the metamorphic complex of Xiaoqinling area is Metamorphic core complex or not.Methods A contrast is made between the characteristics of typical MCC and the Taihua Complex in the Xiaoqinling based on investigation and analysis of structural evolution of the Xiaoqinling.Results The tectonic characteristics and evolution of the Xiaoqinling area do not fit those of typical MCC.Conclusion The Taihua Complex in the area is a metamorphic complex undergone low-angle overthrust from the south to the north and uplifting lately by fault blocking,rather than a MCC. |
