摘要
甘肃李坝金矿是中秦岭褶皱带上一个典型的特大型金矿田,研究其区域和矿区的地球物理特征,对寻找该类矿床具有十分重要的意义。通过对礼岷地区区域重力场、磁场和李坝矿区电、磁场的特征的总结,结合地质成矿模式,提出了该区金矿地质-地球物理模型,该类矿床找矿预测的地球物理标志。
The Liba gold deposit in Gansu province is one of the classic gigantic gold ore fields in middle Qingling fold zone. The study of geophysical characteristics in the region and ore field is of great significance to the exploration of this kind of deposit. Combined with the geo-geophysical mineralization model, the geo-geophysical model is proposed for the gold deposit. The geophysical prediction indicators for this kind of deposit is determijned through a comprehensive summary of the gravity field and magnetic field in Li-Ming region and the characteristics of electric and magnetic field in Liba ore field.
