| 中文摘要: |
| 河北省上官庄菱铁矿床主要赋存层位包括上石盒子组一段、下石盒子组二段、山西组、太原组和本溪组,矿体多呈似层状、透镜状及豆荚状,与围岩产状一致产出,主要的矿石矿物为菱铁矿、赤铁矿,不同层位矿石化学组分因地层在沉积时的环境不同而存在差异。矿床的形成与古地理及古地形条件、水化学条件、岩相条件密切相关,该矿床属于产在陆相含煤碎屑建造及不稳定的浅海相铝土质岩建造中的沉积菱铁矿矿床。 |
| 英文摘要: |
| The host strata of the Shangguanzhuang siderite deposit comprise the first member of Shangshihezi Group, the second member of Lower Shihezi Group, Shanxi group, Taiyuan Group and Benxi group. The orebodies occur in forms of stratiform, lenticular and podiform. The attitude is same as the country rocks. The main ore minerals are siderite and hematite. Chemical compositions of the siderite ore vary in different stratums due to different depositional environments. The formation of the siderite deposit is closely associated with the paleogeography, paleotopography, water chemistry and ancient facies conditions. The siderite deposit belongs to the sedimentary siderite deposit which was deposited in the continental coal-bearing clastic formation and shallow marine aluminum formation. |
