| 中文摘要: |
| 冀北地区银(多金属)矿床成因类型可划分为火山-次火山热液型和岩浆热液型,以火山-次火山热液型为主。银多金属矿床的空间分布受火山断陷盆地或凹陷带内断裂构造的控制,时间上则与燕山期强烈的构造-岩浆活动相配套,矿床由南向北呈铜钼矿→金银铅锌多金属矿→银多金属矿→银矿→萤石矿的空间组合规律。文章总结了典型矿床成矿模式,提出了冀北地区银矿找矿方向。 |
| 英文摘要: |
| Ag(polymetal) deposits in the north Hebei poovince are genetically dirvided into volcao-subvolcano hydrothermal type and magmatic hydrothermal type and dominated by the former.Spatial distribution of the Ag(pdymetal) deposits is controlled by volcano-faulted basin or faults in the depression zone and they are matched with the strong Yanshanian tectonic magmatic activity in time scale.From south to morth ore deposits occur in spatial distribution pattern of Cu,Mo deposit→Au,Ag,Pb,Zn-polymetal deposits→Ag-polymetal deposits→Ag deposits→fluorite deposits.Metallogenic model of typical deposit is summarized and ore-searching direction of Ag deposits in the morth Hebei province is put forward. |
