| 中文摘要: |
| 山东莱芜接触交代-热液铁矿产于中生代构造盆地周边的中奥陶统马家沟组碳酸盐岩与燕山晚期闪长岩接触带及其附近岩石中。矿山矿田的铁矿床可分为4种形态类型、6种构造类型和多种矿体型式。铁矿赋存规律研究表明,大-大中型矿床往往具有复杂和较复杂的矿体形态、单式褶皱背斜和复式褶皱背(向)斜的矿床构造类型,有利的围岩层位为马家沟组五阳山段、阁庄段和八陡段碳酸盐岩,同时矿床有比较大的埋藏深度(多为-200~-600 m),弧形隆起的南、北端和两侧的凸(凹)弯曲部位均为形成大-大中型铁矿床的有利部位。 |
| 英文摘要: |
| the contact metasomatic-hydrothermal iron deposits occur in contact zones of carbonate rock of Majiagou formation of Ordovcian Series and Late Yanshanian diorite and in the rocks near the contact in the periphery of a Mesozoic basin.The iron deposits in the Kuangshan ore field can be divided into 4 morphological types,6 structural types and several ore body styles.The occurrence pattern of the iron ore deposits shows that the large,large-medium deposits are complicated in morphology and they are divided into anticline and anticlinorium types.Wuyangshan Member,Gezhuang Member and Badou Member of Majiagou formation are favorable ore horizons.Generally,the deposits are deeply buried to depth from about-200m to-600m.The large,large-medium deposits are generally located at the plunging end of arc anticlaine and concave and convex curvature on the either limbs of the anticline. |
