| 摘 要： | 老湾金矿带分布于桐柏一大别山（北坡）金银成矿带南亚带，北以松扒韧性剪切带与秦岭岩群毗邻，南以鸿仪河韧性剪切带为界和浒湾岩组相接，金矿带受龟山岩组、老湾花岗岩和区域韧性剪切带的共同控制，形成长23Km、宽0．8～1．3Km、呈NWW向带状延伸的金矿带。金矿带赋存于中元古代龟山岩组中的下岩性段白云石英片岩中，中上部岩性段斜长角闪片岩脆性构造破碎带中有脉状金矿体产出。老湾花岗岩与其在北侧的金矿体关系密切。

| Abstract: | The Laowan gold ore belt distributes along the southern subzone of Tongbai - Dabie Mountain （North Slope） gold and silver mineralization belt. It is adjoin to the Qinling group -complex by the Songba ductile shear zone in the north, and contacts to the Huwan formation - complex by the Hongyihe ductile shear zone in the south. The gold ore belt is closely related to the Guishan group - complex, the Laowan granite and the regional ductile shear zone. It is 23 kilometers long and 0.8 - 1.3 kilometers wide in scale and extends along the direction of NWW. The gold ore belt occurs in the muscovite quartz - schist of the lower member of the Guishan group - complex of the Mesoproterozoic, and the vein gold ore bodies occur in the brittle structural zones of the plagioclase amphibole - schist from the middle and upper members of the Guis- han group -complex. The Laowan granite is closely related with the gold ore bodies in the north. |
