摘要 公婆泉铜矿是北山地区已发现的重要铜矿。从公婆泉铜矿田区域地球化学资料入手,研究了成矿的区域地质环境和地球化学环境,发现成矿元素
异常组合(CuAgAu);指示元素异常组合(CuPbZnAgCd和 WMoSnBi),成矿环境元素异常组合(UPF、FeVNiCr)的空间分布,
从而总结出了甘肃北山地区公婆泉斑岩铜矿田的区域地质地球化学异常结构模式,以用于本区斑岩型铜矿床大范围的成矿预测,对于丰富和完善斑岩铜
矿床地球化学模型具有一定的指示意义。
Abstract :The prospecting for porphyry copper deposits in Beishan area has been paid much attention by geologists in China.
Gongpoquan, an important porphyry copper deposit, was discovered in Beishan area, and many geological prospecting companies have
recently made remarkable breakthrough in the ore-prospecting work in periphery and deep-seated areas, and hence the reserves of
Gongpoquan are being gradually increased. Using the regional geochemical data obtained in the ore field, the authors studied the
regional metallogenic geological and geochemical setting and the distribution regularity of the ore-forming element association
(Cu, Ag, Au), the indicator element associations (Cu-Pb-Zn-Ag-C and W-Mo-Sn-Bi), and the metallogenic environmental element
associations (U-P-F;Fe-V-Ni-Cr). On such a basis, this paper puts forward a regional geological-geochemical structural model for
the Gongpoquan porphyry copper deposit, which is of some significance in enriching and improving the related theoretical models.
