三家子金矿位于冀东金成矿带东部,矿区内分布大量受断裂构造控制的含金石英脉,通过野外和室内研究,确定其成矿物质来源于燕山期岩浆期后热液。这些成矿热液在沿矿区内深大断裂F1向上运移过程中,部分成矿物质在F1断裂沿走向变化处发生沉淀,其它成矿物质在F1断裂派生的次级张裂隙中沉淀。该矿床属于受断裂控制的中低温、岩浆期后热液矿床。
三傢子金礦位于冀東金成礦帶東部,礦區內分佈大量受斷裂構造控製的含金石英脈,通過野外和室內研究,確定其成礦物質來源于燕山期巖漿期後熱液。這些成礦熱液在沿礦區內深大斷裂F1嚮上運移過程中,部分成礦物質在F1斷裂沿走嚮變化處髮生沉澱,其它成礦物質在F1斷裂派生的次級張裂隙中沉澱。該礦床屬于受斷裂控製的中低溫、巖漿期後熱液礦床。

Sanjiazi gold deposit is located in the eastern of gold metallogenic belt of the Eastern Hebei Province, widely developed mass auriferous quartz veins which were controlled by fault structure. We confirmed that the metallogenic materials derived from Yanshanian post-magmatic hydrotherm through wild researched and laboratory studied. Part of the metallogenic materials sedimented when the trend of fault F1 changed, while metallogenic hydrothermal were moved up along the deep fault F1, and other metallogenic materials sedimented in the secondary tensional fracture derived by fault F1. The Sanjiazi gold deposit belongs to the medium-lower temperature and post-magmatic hydrothermal deposit, which was controlled by fault.
