The Danfeng Ophiolite in Shangnan-Danfeng Area of the North Qinling Orogenic Belt: Aerogamma spectrometric and Aeromagnetic Characteristics and Its Geological Significance

  • 摘要: 通过最新获取的1:50000高精度航空磁测和航空γ能谱资料对北秦岭商南-丹凤一带(商丹段)航空地球物理场空间分布进行分析,划分了商丹段主要磁性构造单元和放射性构造单元。根据商南松树沟蛇绿岩的航磁、航空γ能谱场特征,建立了北秦岭构造带的标准蛇绿岩地球物理响应模式,利用该模式对丹凤资峪-郭家沟一带蛇绿岩范围进行了厘定,给出了丹凤蛇绿岩的地球物理学证据。同时推断了分水岭蛇绿岩和鮸鱼嘴-清油河一带基性超基性岩,认为鮸鱼嘴-清油河一带可能残存有蛇绿岩。
    Abstract: The spatial distribution of aerogamma spectrometric and aeromagnetic anomaly in Shangnan-Danfeng area of the North Qinling Orogenic Belt has been analyzed in this paper, and then the corresponding tectonic units has been divided on the basis of high-resolution aeromagnetic and aerogamma spectrometric survey.A standard geophysical response mode of ophiolite complex in the North Qinling Orogenic Belt has been established by extracting its characteristics of aeromagnetic and aerogamma spectrometric anomalies. The characteristics of Songshugou ophiolite show that the ophiolite complex in the North Qinling Orogenic Belt has low radionuclide concentrations and high-amplitude positive anomaly. According the geophysical response mode of Songshugou ophiolite, the mafic-ultramafic rocks in Guojiagou area have been identified as the ophiolites. And then, the spatial distribution of Guojiagou ophiolite in Danfeng area has been delineated by the geophysical evidences that obtained from the high-resolution aeromagnetic and aerogamma spectrometric survey. Meanwhile, the Fenshuiling ophiolite and Mianyuzui-Qingyouhe mafic-ultramafic rocks in Danfeng area have been inferred and interpreted in this paper, and it's inferred that some ophiolites may be existed in Mianyuzui-Qingyouhe area.
