| 研究区大地构造位置位于华北陆块北缘阴山隆起东部、临河—集宁—尚义东西向深大断裂以南。划属华北陆块北缘成矿省(II-3)乌拉山—集宁—阜新太古代、燕山期金多金属成矿带(III10)中部大青山金银多金属成矿带，是中生代火山-次火山低温热液银金铅锌多金属矿的有利成矿地区，矿产资源极为丰富。本文重点以研究区内开花山九龙湾银多金属矿床和豆角山索家沟银多金属矿床两个典型矿床为研究对象，系统分析了矿床地质特征、地球物理特征、地球化学特征、控矿因素及找矿标志，分别从地质、物探、化探三方面指出了区内银多金属矿床的找矿标志，建立了区内银多金属矿床找矿模型。该综合信息找矿模型的建立，对区内及相似成矿背景区域矿产勘查工作提供了一定的参考价值。 |

| The geotectonic position of the study area is located in the east of Yinshan uplift on the northern margin of the north China Block, and south of the east-west direction deep fault in Linhe—Shangyi—Jining district. It belongs to the central Daqingshan gold-silver polymetallic metallogenic belt of the metallogenic province on the northern margin of the north China Block (II-3) Ulashan—Jining—Fuxin Archaic and Yanshanian gold polymetallic metallogenic belt (III10), and it is a favorable metallogenic area for the Mesozoic volcanic-subvolcanic low-temperature hydrothermal silver-gold-lead-zinc polymetallic deposit, the mineral resources are extremely rich. The Jiulongwan Ag polymetallic deposit in the Kaihuashan district and the Suojiagou Ag polymetallic deposit are selected as the typical deposits for further study, and systematically analyzed the geological characteristics, geophysical characteristics, geochemical characteristics, ore-controlling factors and prospecting criteria of the deposit, pointing out the prospecting marks of silver polymetallic deposit from the geology, the geophysical exploration, the geochemical exploration three aspects, and setting up the prospecting model for silver polymetallic deposit in the area.The established comprehensive information prospecting model in this thesis, provides some reference value for mineral exploration in the area and similar metallogenic background. |
