| 摘 要： | 下寒武统层状金矿是鲁西地区继归来庄隐爆角砾岩型金矿以后 ,近年来所发现的又一新类型金矿。该类金矿赋存于寒武纪朱砂洞组灰质白云岩和白云质灰岩中。矿体产出层位稳定 ,矿石类型单一 ,矿化连续 ,具有广阔找矿前景和较大的资源潜力。矿床形成与中偏碱性次火山杂岩及其次火山热液作用密切相关 ,表现为“二长斑岩—断裂裂隙—碳酸盐岩层”三位一体的控矿机制。该类金矿最早在磨坊沟被发现和评价 ,因此 ,笔者将其称为“磨坊沟式”金矿。

| Abstract: | The Lower Cambrian layerd gold deposit in the west part of Shandong Province is another new type of gold ore deposit after Guilaizhuang cryptoexposion gold ore was discovered in this aera. It occures in the gray lime dolomite and dolomite lime of Cambrian Zhushadong Formation. The ore body and its host rock are stable with good continuity. The type of the ore is single. The formation of the ore is relatived with the volcanic complex in the area. The monzoporphyry-fracture-carbonate is the factor of the ore formation. This kind of gold ore was found in a place named Mofanggou, so the authors call it Mofanggou type gold ore deposit. |
