| 中文摘要: |
| 新房金矿床是辽宁省“十四五 ”找矿战略突破行动中新提交的中型金矿床，本文总结分析了已探明的新房 矿段和元和矿段矿体特征，分析认为新房金矿床为韧性剪切带型(叠加后期断裂构造)金矿床。矿体多赋 存于太古宙片麻岩中，矿石类型为含金石英脉及硅化钾化蚀变岩型；基本为隐伏矿体，矿体埋深大；太古 宙片麻岩发育区、近南北向与北西向韧性剪切带发育区及韧性剪切带与新元古界及其下伏太古宙片麻杂 岩之间的拆离断层交汇部位是找矿有利部位。 |
| 英文摘要: |
| The Xinfang gold deposit is a medium-sized gold deposit newly submitted during the "14th Five-Year Plan" Strategic Breakthrough Action for Mineral Prospecting in Liaoning Province. This article summarizesand analyzes the characteristics of the ore bodies in the proven Xinfang ore segment and Yuanhe ore segment.Through analysis，it is considered that the Xinfang gold deposit is a ductile shear zone type(superimposed with late-stage fault structures)gold deposit. Most of the ore bodies are hosted in Archean gneisses，basically being concealed ore bodies with a large burial depth. The ore types are gold-bearing quartz veins types and silicified-potassic altered rock types. The areas where Archean gneisses are developed，the areas where nearly north-south and northwest-trending ductile shear zones are developed，and the intersection parts of the ductile shear zones andthe detachment faults between the Neoproterozoic and the underlying Archean gneiss complex are favorableprospecting areas. |
