摘要:
庙岭—九仗沟金矿带位于华北陆块南缘熊耳山—外方山地区，沿该金矿带F8含矿构造断续产出9个金矿段。由构造切割关系判定，F8含矿构造形成年龄晚于157 Ma，呈现压扭性力学性质，为近东西向挤压运动的结果。结合大地构造背景、构造空间分布特征及区域构造岩浆活动事件，认为F8含矿构造应为伴随燕?狡诨ǜ谥恃医秩攵纬傻耐碣奘馈绨综咽拦乖煅医疃牟铮F8含矿构造向深部仍存在大规模成矿的可能，具备开展进一步深部找矿预测的基础。

Abstract:
Miaoling-Jiuzhanggou Gold Belt is located in Xiongershan-Waifangshan Area along southern margin of North China Block.There are 9 gold ore sections intermittently distributed in F8 ore-bearing structure along the gold belt.According to dissection relationship between fragile structure,formation time of F8 ore-bearing structure is later than 157 Ma.It presents mechanical properties of compressive torsion,and is the result of compressive movement in EW orientation.Based on tectonic background,tectonic spatial distribution and tectonic magmatic events,it indicates that the formation of F8 ore-bearing structure should be associated with granitic magma intrusion in Yanshanian period,and the result of tectonic magmatic activities in late Jurassic-early Cretaceous.There is possibility of large-scale minera-lization in the deep F8 ore-bearing structures,and the foundation for further deep prospecting prediction.
