| 中文摘要: |
| 赤峰—朝阳金矿化集中区是我国重要的金矿产地之一,于家营子金矿区即位于该矿化集中区的中东部。对于家营子金矿床地质特征及矿床成因类型的分析研究表明,区内黄铁矿化、硅化蚀变强度与金矿化呈正相关关系；矿床属于含金硫化物蚀变型金矿床。研究结果认为,区域太古宙变质岩的潜在含金性、花岗岩类多期次的活动以及长期活动的断裂构造系统是该矿床的主要控矿因素。文章指出了该区今后的找矿方向。 |
| 英文摘要: |
| The Yujiayingzi gold deposit is located in the eastern of Chifeng-Chaoyang gold mineralization concentration area which is one of the important gold-producing areas in China. Based on the study and analysis of geological characteristics and genesis of Yujiayingzi gold deposit, it is concluded that the deposit belongs to the auriferous alteration type gold deposit, and there is positive correlation between gold mineralization intensity and pyritization and silicification intensity. The study result indicated that the main ore-controlling factors are as followings:(1) gold-bearing source strata - Archean metamorphic rocks; (2) multi-stages of magmatic activities; (3) long-term structural system activities. Finally, the author pointed out the prospecting targets in the deposit area for future exploration. |
