| 中文摘要: |
| 对冀北牛圈银金矿和营房银铅锌矿矿床特征和相互关系的研究认为,营房矿体西部的硅化体及硅化花岗岩质角砾岩系成矿前断裂F1形成的,由于成矿后断裂F2大幅度的右行推覆作用,使原处于同一水平上的银金矿,在营房矿区被掩埋在深部,而深部的银铅锌矿却被推移到了浅部目前的位置;牛圈银金矿深部的铅锌矿未受到后期F2断裂的波及,可能完整地被保留在深部原位。根据地质、地球化学研究,提出了"在牛圈矿体深部找营房矿体,到营房矿体深部找牛圈矿体"的深部找矿方向。 |
| 英文摘要: |
| According to characteristics of Niujuan Ag-Au deposit and Yingfang Ag-Pb-Zn deposit in the north Hebei province and relation between them it is considered that the Ag-Au and Pb-Zn mineralization occur at the same horizon originally; the silicified body and the silicified granitic breccia in west of Yingfang Pb-Zn deposit are formed by the pre-mineralization fault F1; the right hand overlapping of post-mineralization fault F2 buried Ag-Au mineralization to depth and overthrusted the Pb-Zn mineralization to shallow and the two type mineralization under truncation of F2 may remain at depth. Therefore, prospecting of Pb-Zn ore bodies to depth of Niujuan Ag-Au deposit and prospecting of Ag-Au ore bodies to depth of Yingfang Pb-Zn deposit are put forward in this paper. |
