摘要
受现代地磁场磁化所产生的岩石样品中的剩磁 ,其方向与现代地磁场一致 ,测定并分解出岩样中的现代地磁场剩磁分量就可以确定岩石样品的产状。以安徽五河荣渡金矿为例进行了尝试 ,并据此建立了荣渡金矿区基岩构造和控矿构造格架 ,其结果与区域构造相协调。由此确立的荣渡金矿受南北向断裂控制的认识已被后来的找矿工作所初步验证。
In this paper, the authors try to analyze the buried structures after determining the attitude of the sedimentary rocks and of the schistosity by measuring the remanent magnetization in core samples from the Rongdu gold deposit, Anhui. The results agree with the tectonic framework of the region. And the conclusion about the NS-trending structure controlling over the gold ore has also been comfirmed by late ore-searching activity.
