摘　　要：新发现的王家湾锑矿区,目前已共圈定锑矿体4条。矿体长80m~250m,矿体厚度1.55m~2.89m,矿体品位1.57%~3.72%。矿体均赋存三叠纪大河坝组的粉砂岩、细砂岩及砂质板岩中,位于深大断裂带的边部,总体受深大断裂带的次级近东西向断裂控制呈脉状产出,矿体产状与围岩产状基本一致。初步认为与崖湾锑矿同属热液脉型矿床,矿区找矿前景优越。A total of 4 antimony ore bodies have been delineated in the newly discovered Wangjiawan antimony mining area.The ore body is 80m~250m long,with a thickness of 1.55m~2.89m and a grade of 1.57%~3.72%.The ore bodies are all hosted in the siltstone,fine sandstone and sandy slate of the Triassic Daheba Formation,which are located at the edge of the deep and large fault zone.They are generally controlled by the secondary nearly east-west faults of the deep and large fault zone and occur in vein shape.The occurrence of the ore body is basically consistent with that of the surrounding rock.It is preliminarily believed that both the Yawan antimony deposit and the Yawan antimony deposit belong to the hydrothermal vein type deposit,and the mining area has excellent prospecting prospects.
