| 中文摘要: |
| 福建政和上山岗金银矿位于政和-大埔深大断裂带东侧的东坑火山盆地中，为受断裂控制的火山-次火山热液型金银矿床。通过对矿区地质构造的研究，认为矿区断裂发育，主要有NE向、NW向、近EW向和近SN向4组，均为控岩-控矿构造，为矿区内重要的找矿标志。其中，NE向和近SN向断裂为主要的控矿和容矿构造，NW向和近EW向断裂为主要的控岩构造，常切割破坏矿体。金银矿体（脉）的产出严格受火山盆地中的断裂控制，与赋矿围岩的具体岩性关系不明显；矿体（脉）的大小与所在断裂的规模密切相关。矿区外围及深部与主干断裂平行的次级断裂可作为矿区进一步找矿的有利构造。 |
| 英文摘要: |
| Shangshangang gold-silver deposit is located in Dongkeng volcanic basin in east side of Zhenghe-Dapu giant deep fault zone. It is a volcanic-sub-volcanic hydrothermal gold deposit controlled by fault. Four sets of fault trending NE, NW, roughly EW and roughly SN are developed in the area and control the rock-forming and ore-forming processes. They are the most important prospecting marks. The ore is mainly controlled and hosted by the NE and SN faults. The NW and nearly EW faults are important dyke-controlling structures, often cut and destroy ore bodies. The gold-silver ore bodies are strictly controlled by the faults in the volcanic basin having nothing to do with lithology of the surrounding rocks. The size of the ore body is closely related to the fault size. Surroundings of the deposit and sub-faults parallel to the main fault are potential for further exploration. |
