| 摘 要： | 在收集整理中国大陆上十几条地学断面、数十条地震剖面、大地电磁剖面、地壳上地幔剪切波资料的基础上，对含金矽卡岩矿床的深部地球物理背景进行了深入的研究，作者认为岩石圈剪切带是控制含金矽卡岩矿床的最主要的深部地球物理背景条件。壳内低速高导层因与地幔流体分布有关，同样对含金矽卡岩矿床有控制作用、大（ 深） 断裂带的交汇部位控制着与矿有关的中酸性侵入岩浆，可以利用这些因素的共同制约作用进一步圈定含金矽卡岩矿床和铜伴生金矽卡岩矿床分布的远景预测区。

| Abstract: | Based on collecting and arranging data from more than ten geoscience transects,tens of seismic profiles and magnetotelluric profiles as well as crust upper mantle shear waves,this paper has made a thorough study of the deep geophysical background of the auriferous skarn deposits.The authors hold that the lithospheric shear zones constitute the most important deep geophysical background of the auriferous skarn deposits.Being related to the distribution of mantle fluids,the intracrustal low velocity high conductivity layers control the auriferous skarn deposits,whereas the intersections of large (deep) fault zones control mineralization related intermediate acid magma.The joint restriction role of these factors can be used to delineate prospect araes of auriferous skarn deposits and gold (copper) skarn deposits. |
