补充资料：层控矿床
| 层控矿床 stratabound ore deposit 受多种成矿作用影响，受一定地层层位控制的矿床。其矿体产状可以严格与地层一致，呈层状、透镜状或条带状；也可以不一致，呈不规则状或网脉状，但都局限在某一固定地层单元中。层控矿床常是多成因的，是以外生成矿作用（沉积成矿作用或火山-沉积成矿作用）为基础，又受到内生成矿作用包括岩浆、变质和热液等作用的叠加改造而形成的复成因矿床，兼有同生矿床和后生矿床的某些成矿特征。矿源层的存在也是层控矿床的重要特征，但矿源层和贮矿层可以是同一层位，也可以是不同层位。层控矿床类型主要有：①沉积或火山-沉积热液叠加改造型层控矿床。它既保存了沉积或火山-沉积成矿的某些特点，又有后期的与热液活动有关的矿化叠加其上 ，如中国湖北黄梅菱铁矿矿床 。② 喷流-沉积型层控矿床。成矿主要与海底喷流-热泉活动有关，与火山作用常相伴随。该类矿床产有铜、铅、锌、金、银、锑、汞、铁、锰等矿产，有重大经济价值，如日本黑矿型矿床。 |
