| 中文摘要: |
| 大石板赤铁矿床位于扬子准地台的东南边缘黔南坳陷腹地之独山箱状背斜次级褶皱大石板背斜东翼，呈层状稳定产出，为沉积型铁矿。赤铁矿层仅见一层，被F2断层横切，形成Ⅰ号和Ⅱ号两个矿体。通过对含矿层位展布及矿石特征分析，结合沉积相与古地理环境等研究，认为大石板铁矿是在湿热气候条件下，各种赤铁矿泥晶等围绕核心以胶体化学方式发生沉积形成赤铁矿鲕粒，经波浪、潮汐等动力最终在近滨远端环境下形成矿床。 |

| Dashiban hematite deposit located in the east Dashiban anticline in Yangtze platform，it occurred as stratiform and is sedimentary iron depositThere is only one hematite strata found and cut by fault F2，formed 2 orebody：ⅠandⅡBy analyses the ore-bearing strata and mineral characteristics，for the study of sedimentary facies and palaeogeographical environment，it’s thought that the formation of Dashiban iron deposit is in the humid heat climate，different hematite slime deposited into oolite as colloid chemical method，then formed in the near shore environment by wave，tide and other dring force |
