| 摘 要： | 凹子岗锌矿床为近年来在湘西鄂西地区发现的具有代表性铅锌矿床,锌矿体严格受地层层位及岩相古地理条件限制,震旦系上统灯影组二段为主要含矿层位,局限海台地潮下相有利于锌元素的原始富集,滩后斜坡或潮道中的角砾状云岩为工业锌矿体形成的必要条件。矿床地质特征显示本矿床为沉积改造成因。水系沉积物锌异常、闪锌矿淋滤后在地表岩石表面所形成的暗红色锌晕等为该类矿床的重要找矿标志。 |

| Abstract: | Aozigang zinc deposit was found in the area of the west of Hubei and Hunan Provinces in recent years,which is the representative lead zinc deposit.The zinc ore bodies are strictly confined by the strata location and the litho-facies paleo-geographic conditions,and are mainly hosted in the second member of the Dengying Formation of the Sinian system.Restricted marine platform sub-tidal facies make for the zinc primary enrichment.The breccia-shaped dolomitic rock in the slope behind the beach or in the tidal channel is the necessary condition for industrial zinc ore body formation.The geological characters of deposit indicate that it is a sedimentary reconstructive deposit.The important prospecting indications of the deposit type are abnormal zinc of watery sediment and dark red aureole which is formed by zinc ore eluviation in the surface of the upper rocks. |
